Looking for a game to play. I have a PS3. A decent story is important. Linear gameplay/not a sandbox. Definitely no turn based combat. As little level grinding as possible. On the easier side of the difficulty spectrum. Non-cartoonish art style if possible.
I greatly enjoyed Final Fantasy XIII and XIII-2 on the RPG side of things. If you're looking for MORE of a challage, I highly reccomend Demon's Souls and Dark Souls. Ridiculously hard, but at the same time, once you overcome anything you feel like you actually acomplished something.
On the complete opposite side of the spectrum, Katamari Forever. You play as a cosmic prince pushing a ball that you use to roll things up to make a bigger ball so that you can roll up larger things. Probably one of the goofiest game series I have ever played, and most likely my favorite too.
