The reason the game was so popular in the anime and during the games is because it lets you fully immerse yourself within The World. If they could duplicate that kind of technology, then they probably would make a good game. Who wouldn't want a full sensual experience in an online world like that, really? Fight monsters with your own two feet, or whatever. Though the games themselves were limited by only what you could do in the game, I think the actual game The World allowed a lot more freedom.
