1) Ratchet

2) Uncharted

I'd be hesitant about AC. Rent it first. It's very buggy, with some serious framerate problems. I'd just ahead get the two games made by two of the best game developers out there. Ratchet and Uncharted.

If that doesn't convince you, then whatever. These "convince me" posts are rediculous. Herd conformists are amusing.

neither. I have no idea why anyone would spend all day playing a video game about a half-wit gangster.

If that's a fun time, then how about some other games:

Epilepsy-Damashi

World of Wheelchairs

Multiple Sclerosis Hypnosis HD

Captain Tourettes and the Autistic 4.

Syndrome of a Down

AIDS Quest

Skid Row

Wow, I'll be rich!!!

My "A" list.

Resistance - I still play it. I think it's a great game single player (and you can play the single player mission in co-op mode)

Ratchet & Clank - Very awesome. Still playing it. Graphics, gameplay, hell yeah.

Uncharted - Love the graphics and the gameplay. The taking cover stuff takes some getting used to but it's a very awesome game. I'm playing it again.

Rock Band - If you're not into these types of games, don't bother, but it's amazingly fun if you like music games.

My "B" list.

Folklore - I thought this game was awesome.

Virtua Fighter - Fun fighting game

Motorstorm - I know you have this one. This is almost in my C list, but there are some good redeeming qualities.

My "C" list.

Assassin's Creed - Almost "D" list. If you can get over the bugs and the crappy frame-rate, and somewhat sloppy controls, there is a pretty good game in there.

Warhawk - Contrary to others, this wasn't really my favorite game in the whole world, but it is very fun in short bursts.

ifonline is a big consideration for best value then go with Resistance or COD4. My personal preference is Resistance. Technically I feel it's a better multiplayer experience. But, it's opinion, so take with a grain of salt.

If you don't care too much about online, then I suggest Ratchet, Uncharted or Asassins Creed. All three games give you MANY reasons to play over and over again. The most being Ratchet. I'm being serious, I'm still playing Ratchet because I haven't unlocked every skillpoint or collected all the secrets yet. I'm really trying hard to find the last shard to make the ultraweapon but haven't found it yet :).
