The new game (EU version - Dark Conflict) is out!!
Now for me, advance wars has always been one of the best games out there - and this is no exception. I could give a looooong review on it compared to AWDS but I won't XD

In short, this game is a hec of a lot more balanced, the AI doesn't cheat, and once you've gotten used to ALL the changes - it's serious fun.

Did I mention you can play wifi too?
My wifi isn't working right now ;___;

But yes, you can play against people random ranks or the same as you - and trade maps with those who have your friend code. The map editor is also a lot better.
