I suppose you all mean singleplayer? Sometimes those little skirmish games can get to be tricky. I always hated fighting Americans, they dump like a million little people at you about everyone 2 minutes. Now RA2 online, wow, omg, even noobs are hard to beat there. And I naturally hate Brits, Lib's, Raq's, and Germ's. In game of course, easiest is them bloody Russians.
And these kids sound like they haven't got a clue about what RA2 even is, or even know what they want. So I'm guessing, they are probably hyper, and RA2 is not a hyper game.
And you may not think about it, but you are using your fat little noggin when you play C&C games. That rush, was just planned. That sniper just outside base perimeter, planned. Now I personally, am not a person who rushes with large amounts of small things, I build up my base, get defenses, get my economy going, then I build a few big things, like 4 Kirovs or 4 Dreadnoughts, and send those in to pick on the enemy, GI's are for defense in my world. I tend to end up with barely any losses.
Planning world domination needs patience, and thats something a 13 year old hyper sugar'ed up kid does not want to do.
