myself and a few friends we play thru hamachi and we play games in t/mode with all players on random creates an interesting challenge not knowing who you are going to get and who you are playing. But at a pinch i would rate Flame as number one and assault as number two followed closely by stealth.
when we play thru hamachi we always play t/mode and start with 10000 cash makes for very interesting and strategic games. I like t/mode as it greatly reduces unit spamming and forces you to use your army with greater care.
Just had a game with a friend.i was assault he was research gen.now when my dozer's had built a certain amount of defense's(sorry didn't keep track of the exact number) a message came up on the dozer's defense command set that this up-grade had already been purchased so i couldn't get to the defense menu to build more.not a big deal as i could just build more dozer's but it happened each time with the new dozer's. i ended up with alot of dozer's sitting around the battle field doing nothing but making for great target practice for my friend.
