Research & Development Discussion - Delta+1

FEEDBACK WELCOMED

Hello everyone. I’ve been lurking here for years and wanted to reach out and get some feedback from our house rules on new tech development house rules for use on our Anniversary map. We went out to solve 2 problems, 1) the randomness of tech breakthroughs and 2) the game changing ability of certain techs. We wanted a system where you picked what tech your research with some sort of progressive path to a breakthrough. We have 20 techs that can be researched (at 1 per turn) in 4 categories, land warfare, air warfare, naval warfare and “special”.

Most of the tech breakthroughs provide advantages only in the first round of combat and we think provide some flavour to the game but I wouldn’t mind getting some more eye on this to see if anything stands out as too powerful or not worth the 4 + IPC investment.

We’ve played 3 games now with the progressive research model and it’s been fun.

I should add that while we play on the Anniversary map (neither of us have room for Global unfortunately), we use the following rules from other games or house rules.

Tanks cost 6 IPC Industry have built in AAA AAA unit from 1942.2 SBR Escorts and Interception BB has built in AAA, rolls 1 dice at 1

Last note is we wanted to increase abilities without adding new units to the game. The map just gets too crowded once you start including new units.

Would welcome any thoughts you have. Thanks in advance!!

**** New Tech Research Rules ****

To make an investment in a technology, the player spends 4 IPC to start a project, limited to starting 1 project per turn, however doesn’t announce with projects they are starting, places a country roundle on the progress tracker starting at Phase 1. Players can only have 1 ongoing project per category (Land, Air, Naval, Special). During the research phase, the player rolls 1 free dice for each research project and may purchase as many additional dice rolls as they want for each of the research projects prior to rolling (see additional dice cost below). The player needs to roll the number on the progress chart and if achieved, the country roundle is placed in the “breakthrough” box. If roll is not successful, the country roundle is moved up one and each subsequent turn achieving a ‘breakthrough’ becomes easier. If the player gets to Phase 3 without achieving a breakthrough, the roundle is moved to the DELAYED box and the technology is achieved in the research phase of the next turn. Having a tech in DELAYED does not block a new project in the same category from being started.

While the progress of each step is announced, including a breakthrough, the player does not reveal the technology breakthrough until the technology is used. For tracking purposes, keep your breakthroughs in the “secret” box until it is used then move to “revealed’.

@doomer1940 I agree with you I’m working on fixing it

We use our own tech charts that are country specific. This is for Global 1940 but could be adapted to any game.

Germany
2 – The jet age begins and the ME-262 takes to the skies. Fighters defend at a 5 during ground attacks and scrambles, and defend at 3 during strategic and tactical bombing.
3 – King Tiger tank is developed and rolls off the assembly line. Armor now attacks on a 4.
4 – Type XXI U-boat is unleashed upon the Atlantic. Submarines attack at 3 and defend at 2.
5 – Nebelwerfer rocket packs delivered to the front. All artillery can support 2 infantry or mechanized infantry.
6 – Waffen SS divisions now attached to regular army divisions. “4+1” For every 5 infantry in a combat or defense. One attacks and defends at +1. With an attached artillery the attack value is increased to 3.
7 – V-2 Rocket is developed. Airbases may now conduct one industrial or naval/air base attack on a zone within 4 spaces. One die of damage is rolled per German controlled operational air base.
8 – Long range aircraft. All aircraft flight range is increased by 1 movement.
9 – Advanced radar. AA guns hit at 2 during strategic and tactical bombing raids.
10 – Improved mechanized infantry. All mechanized infantry attacks at a 2. Artillery do not boost.
11 - Improved aviation engineering and manufacturing. Fighters now cost 8 IPC.

12 – Atomic weapons. A new age of terror begins as the Nazis harness the power of the atom.
Atomic bombs cost 24 IPC to build. Only two may be built per turn. May not be built on same turn as breakthrough turn.
Move as infantry by land or sea. If loaded on a strategic bomber, it can move the current range of the bomber
Due to a lack of trained technicians and engineers, a nation may possess no more than 2 weapons at one time.
Due to the size and nature of the airburst associated with the nuclear warhead, no attack roll is required to score a successful hit.
No air defense, such as fighter scramble, is allowed due to the altitude of the strike plane and surprise of the attack. Only upgraded fighters may intercept. Long range aircraft or jet power technology must have been researched.
An atomic weapon is treated as an AAA gun if the territory in which it is stored is attacked. 
No AAA guns are to be fired due to the altitude of the strike plane and surprise of the attack only normal AA gun with factory can fire. Airbase and naval base do not fire AA.
Any industrial complex is attacked with 4 dice disabled to maximum value of 20 for major and 2 dice disabled to maximum value of 6 for minor complexes.
Any airbases or naval bases are attacked by one dice of value.
One dice is rolled and that number of units of defenders choice eliminated. AAA guns may be chosen.

If used on a naval assault:
The nuclear strike cannot be combined with surface vessels.
Due to the altitude of the strike plane and surprise of the strike, aircraft on carriers and loaded troops on transports are considered to be cargo and provide no defense. The 5 hits are assessed and the attacking bomber returns to base. No 2nd attack is permitted.
Transports chosen last.
USSR is not permitted to develop weapons until they are in a state of war.
1 – IL-2 Sturmovik rolls off the line. All fighters now attack at 4 when paired with a matching armor.
2 – T-36 rolls off the line. Tanks now attack at 4.

Sorry everyone, I will need to push my deadline to another week, there is a lot involved in preparing the illustrator file to work in artscow. I will do everything I can to make these cards available to everyone here as soon as possible.

@Razor:

Maybe the inherent Carrier defense value should be boosted, to compensate for the weaker fighter. Let say you can land 2 planes on the Carrier, but the Carrier itself has a little fighter force just to close combat self defense, making the carrier defend on D3 ?

Very good idea: it is a can opener. It gives much room to compensate.
Maybe you can even give it the classic A1D3, if necessary for balance.
Or even going that far: A2D3, so almost all of the OOB A3D4 Fg + A0D2 Cv= A3D6, will be converted: Fg A1D2 + CV A2D3 = A3D5.

Just suppose that there is a bunch of escorting ship/fighters wich can not be separated from the Carrier unit.

It can probably solve a lot of balance problem.

@Young:

@Vance:

Not certain, but it might have been me.  I voted for emergency conscripts soon after the poll was posted.

Than maybe he didn’t, but I’m not going to run a 3 day poll for 2 weeks or who knows how long, it was his fault for getting booted, that’s my opinion.

fair enough.

I think that radar is a little weak. Perhaps make it a minor tech? Or make radar activate always active AA guns. That would be scary.

Sign ups have begun.
