Actually the controls worked really well except for on the giant walkers with all those hard points and couldn't be added to control groups in either version. The few problems like that were more tied into core game design though. Overall the game has a nice three unique race vibe, if it otherwise is a touch generic, but god the framerate. Even with next to nothing happening the game always had that feeling of sluggishness that you know isn't quite right, playing the PC demo was proof enough of that, but then just gets crippled at points. Not like it even gets ok at any point. I'm glad I Gamefly'd it instead of buying it, was really excited for it too.
Now provided World in Conflict can get the controls this tight and the frame rate running well that's going to be awesome on 360. Hopefully they realize giving up a little bit of shiny effects to make the game playable is a smart trade off. Granted Massive seems to actually get it unlike so many devs.
