Need advice, kind of lost with my ps3

I got my Ps3 a couple months ago. I got GTA IV and Metal Gear 4 with it.

Metal Gear 4 was amazing. Love GTA IV, current playing it. I want to get more games though.

Right now I just play GTA IV and use the Ps3 as a movie downloading thing. Normally I order a movie off the service once a week. I love that feature. I love that I can download movies in like a hour and watch them on my PS3.

Game wish I kind of feel lost though. I need some advice there. I need some games.

I need to be introduced to the real reason why I got the system, the games.

If anyone can give me some advice on where to go from here, what games that got you to love this system, then I think from there on out I'll be fine. I just want some more games basically and need to be pointed in the right direction.

I prefer sports games, first person is fine. I like everything pretty much besides RPG's and cartoon games.

Even older games I mean would be fine as well. Games that made you love this system.

Thanks.

Heavenly Sword

Burnout: Paradise City

COD4

Definetly Call of duty 4. Another good FPS to try would be Bioshock if you haven't played it on another system.

My first love on the Ps3 would have to be Uncharted and I would recommend that as it is quite cheap nowadays.

Maybe try Killzone 2 since you like fps.
