The only wargame I endorse is Adavanced Wars (1 and 2) for the GBA. Haven't played Dual Strike for the DS but I'm sure it's rocking. Ran thru the 1st AW and am now mostly thru the 2nd game. So good. There's a demo for this new comp wargame called Defcon and it looks kinda fun. Gonna give that a go. Is there a Blood Cricket game you can also bring to the con? I would love to try it out.
