How do I add games to my profile and how do I put those tags on for the systems I own? I'm going to be broke because I'll be buying everthing that comes out...too many games.

To add the tags for the system you own should be somewhere in your 'editing profile' i believe.

To add games, search up your games (on this site of course) and when you get to the game's main profile page at the bottom left side there should be the option to '(add)' it.  Its in red.  Its small and hard to find at first, took me awhile to figure that out.  And of course make sure select the version of the game you own if its on multiple consoles, when you search the game. =)

Thanks

There are plenty.

Must haves, from my experience:

Uncharted 2
Assassin's Creed II

Everyone else loves these, I haven't tried them:

Valkyria Chronicles
