I didn't think I would like Counter-Strike before I tried it, but it definitely surprised me. Probably what I found most surprising was that it's such a hardcore, skill-intensive, simulation-like (not so much in how it handles weapons but in how it handles the whole terrorism/counter-terrorism gameplay) game and yet was so ridiculously popular- I was expecting something more along the lines of a better Halo on the PC (of course, that prepositional phrase denotes why it would be better, xD) but got anything but- other than the obscenely annoying voice chat from 10-year-olds... But, yeah, it definitely surprised me- it's a pretty good game, imo, but that's just my taste.
