I really dig this game. I haven't played it in ages, but I remember having a lot of fun with it. I used to play Allies exclusively, but I got curious about the little Explodey Remote Controlled Tanks. They're absolutely hilarious! That Axis really do have a lot more things to have fun with.
Towards the end of me playing, friends and I would just do skirmishes against AI. My new favorite strategy was to create 10- 15 Nebelwurf (sp, don't remember the full name :/ ) Rocket Batteries, and rain down destruction on entire areas at once! So satisfying!
Then the huge tanks with the giant rocket racks on the top... Another of my favorites. Able to blanket bases with rocket fire. This was always my favorite tactic - To cover and overwhelm the enemy with death from above!
