As from what i've seen in the demo videos, they've played left 4 dead 2, cod black ops and motorstorm?. I'm pretty sure the experience is similar to the wii controllers.

Been using it for a year now, never had any problem before. Some users reported a lot of problems with their mamba, problems such as jitter etc. but i never had any problem till now(touch wood, haha). What do you mean by lag issue with wireless? If u meant that the thing is slow to respond, i don't think that this mouse has that problem. Anyway, if you're getting them, i recommend getting a hard mat such as the ironclad to pair with it.
