I would have agreed with you on the bolded statement a year ago. After playing Halo Wars, however, I began to understand that a controller was enough IF the right company was able to re-think how a controller could be used with an RTS game. I've sent thousands of hours on PC/Mac based RTS games, and Halo Wars felt more intuitive and natural with a controller than those games did with mouse and keyboard. I guess RTS creators just couldn't think outside the box enough until recently.
Personally, I believe World of Warcraft *could* be done well on a 360 or PS3, but that Blizzard simply doesn't need to worry about the incremental money they would gain from porting/supporting on consoles, not to mention the increased costs of doing so.
and somebody in Korea does 600 actions per minute with every move making sense in the SC2 beta atm, you can't do that with Halo Wars, you are gimped by the controls hence making it more console casual friendly( and WoW is as causal as it can get as a PC game lawl,) just like the FPS, the TPS, the WRPG on consoles, basically all western games. In a competing environment which a lot of the PC games are centered around, game pads are ass. World of Warcraft is all about key binding, macros, reaction times and the tons of spells you have to use to counter many things in pvp with every millisecond counting, or sometimes pve, it'd be a gimper game on consoles. They don't care about the money since they are rich to start with, they are free to do what they want instead of having to bring a lesser experience which is against their ideals as game makers, that's why they are one of the top devs in the gaming industry.
