i would say world of goo, if you want to have a unique and challenging puzzler game with some good replay value (you can always try different ideas and approaches to try to beat a level, and even after that, you can try shooting for the ocd's in the levels, which just stands for obsessive completion distinction in the game :D).
above all, i think you'd get your moneys worth with world of goo. i've pored like 20 hours in it so far.
come try out the computer game i've been working on for my high school senior project, titled sling ball. http://vgchartz.com/forum/thread.php?id=47568
