I wish they would allow support for keyboard and mouse. I mean how hard can it be? To solve unbalanced issues in multiplayer they could make it that only controller players can play against other controller players and vice versa.
That cuts the player base, though, right? So... there are less people to play against=longer wait times for games.
As to RTS games on consoles, I think they can be VERY good. I remember Command and Conquer on N64. I LOVED that game and had a BLAST playing it, even though it was single player. I think they had the N64 pad configured VERY well for the game, and I can see the 360 pad being the same.
