kcdzim, I agree with alot of what you said. However FMG has hinted that they will make a tech set, so my suggestion was a simple 12 mold set that people have pretty much been wanting since the original A&A in order to visually represent tech wheather they are using house rules or not.
What it comes down to is what people want from a tech pieces set? I think it is important to discuss these things now so there isnt any overlap or confusion.
There is gonna be plenty of armor and artillery for unique heavy tanks and artillery with the individual nation sets. If you just want nation specific jet fighters, i dont think that qualifies as a tech set.
cminke, why would the BM-13 be used as the mech unit? its artillery. There are plenty of other amored cars and light tanks that could be used.
And yah the type XXI would be a good alternate to the I-400, I just picked the I-400 because it is very large with an extremely distinctive feature and so that at least one of the tech units was Japanese.
