I game. I tend to enjoy first-person shooters the most.

Unnecessary Clarification on Rating System:
5.0: Close to perfect as games can get, at least IMO.
4.5: Truly incredible games, these are must-plays for everyone.
4.0: Games that above their average competition. Highly recommended.
3.5: Purely average. Games that aren't revolutionary or ground breaking, but still good fun regardless. Still recommended in general, but more focused on fans of the particular genre/franchise.
3.0: Games that can be fun, but with some caveats. I'd only recommend these games to specific niches of people.
2.5: Games that just fall short of being good, but aren't quite in the realm of 'bad' yet. I wouldn't recommend these, even if there are small doses of fun that can be found.
2.0: Games that just don't cut it. These ones have major fundamental problems that keep them from being good. Avoid these.
1.5: Games that are painful to play. Can be metaphorical or literal.
1.0: Games that are 'literally' unplayable.
0.5: Games that are so bad they wrap around to being funny and enjoyable (aka the Sonic '06 rating).
