Seems some ppl have made bad experiences ...
I use sometimes the beamer (projector) on my workingplace for wii gaming sessions with co-workers. (Of course after the work is done ...) The picture is bigger and I think it's better suited for local multiplayer with motion controll than a TV. However the light can really be a problem. Playing dark games with a projector is not recommended. Usually I play games like Wii Sports, Wii Sports Resort, NSMB Wii, Mariokart, Boom Blox, Wario Ware or Metal Slug Anthology with my co-workers. All are games, were the graphics really don't matter and all have bright graphics. Oh and placing the sensor bar might be a little bit tricky, but it is doable. A wireless sensorbar should be a great help.
However, for normal single player or online multiplayer gameplay I would use a TV.
PS: My brother has an HD-beamer, which seems to be better quality than the ones we have at work. However I havn't tried it with my Wii.
