However, two weeks is still enough time to get addicted to it.
By the way, people play games for challenge. Go look up a definition for "game". Yes, enjoyment is a huge part, but I just wanted to clarify.
Without challenge, there is no game. Either way, what one thinks of a games quality and enjoyment are very subjective - however, no matter what one person gets from a game, there is a distinct difference between quality and enjoyment. Just because one person doesn't like a game's art style, ambience, game mechanics, level design, etc. does not mean it's a bad game, they just think it is. It could very well be the most talently built thing on the planet.
What I'm trying to say is, if a game is perfectly sound and built (and there are a lot of set rules in game design that can distinguish a game from good or bad) with talented art direction and design, then a person could be absolutely wrong in thinking it's poorly built just because they don't like it.
