This isn’t the place to ask questions -
two of us are trying to play a game, here
1) Yes. Any ground unit can attack any air unit that is on a territory
2) Every time a power conquers territory the IPC earnings totals are changed. If Russia takes a German territory worth 2 IPC’s, then the Russian income is moved up 2 and the German income is moved down 2. You collect income at the end of your turn, so you will get more IPC’s for each territory that you conquer during your turn. You can save money from turn to turn if you do not spend it all.
3) You roll a die for each unit in the battle. If you are attacking with an artillery unit, for example, you need to roll a 1 or a 2 to score a hit. Each hit scored results in a lost unit for the enemy.
4) Every power has a starting IPC amount. One of the powers has to go first. The starting units and money was all taken into account by the maker of the game in attempting to make a game where each side has about the same amount of power and money. Yes, you can have one player play an individual power, so Spring 1942 can have 5 different players - 3 on 2. The players need to work together to be effective.
Axis and Allies is a blast. It is a very fun strategic game that has the proper balance of skill, strategy, simplicity and fun. This game is child’s play compared to a lot of other war games out there, but if the hardest game you’ve ever played is Risk, you may be overwhelmed.
Ask all the rules questions you want in a rules or FAQ thread, or you may private message me any time. As you can see, I’m a “rules deputy” on this site - I know the rules for AA50 and Spring 1942 thoroughly and have played various versions of Axis and Allies for many years. But this is a game-playing thread, as I said before, so rules questions don’t belong here. Thanks, and happy gaming to you.
