I would go with ZOE. What I\'ve seen of crazy taxi hasn\'t impressed me that much (no I haven\'t played it), but I own ZOE, and am very happy with it and the MGS2 demo. I\'m on my second run through ZOE - hardest difficulty, trying for a perfect set of report cards, it\'s nigh impossible, but still really fun. On easier levels the game can be finished in 4-5 hours, but it\'s still great. As for MGS2 - I still spend hours just messin\' around, trying to find new things, and enjoying the breathtaking amount of detail in the game.
