I bought a projector the other day and plan on hooking my wii up to a big fat image (probably around 2.5m by 1.5m). I was wondering, though, will pointing games remain accurite to the edge when the screen is this large? I have seen YouTube videos of ppl playing on massive cinema screens, but it was always wii sports games that did not require point-and-shoot control. Has anyone used a wii on a large screen with something like a FPS? is there a certain distance you have to be for it to work?
