@Blacksaber: Yeah, Wii Sports is another good example in terms of immersion.
At the local games store, they have a PS3 with some tennis game's demo on. Every time I pass by there, there are some kids playing it and I can't help thinking that I'd never be able to play a game like that, not after playing Wii Sports.
@Kurakasa: Don't worry, screens will disappear too one day ;)
