SIMULATION is very entertaining, and it gives the illusion of reality, especially in games. I played a boxing game on wii one time, it felt very real, that I start sweating! it was close to real experience than traditional video games were I did not move much.
Also simulation seems like a good technique for a beginner artists to start with. It simulates natural world dimensions, process, or systems.
I think it will keep developing as an art form because it gives people a chance to live the artist experience, and give the artists new tools to deliver their messages more clearly and closely. I would use it to imitate human movements; like athletes, dancers, singers and extreme-sport performers. I would like understand there experiences with out taking the real risk.
