Recommend me some PS3 games

[KingDrool]

Demon's Souls. I like it better than Dark Souls, and it may be my favorite game on the console. Challenging as hell, but totally awesome.

3D Dot Game Heroes. Awesome spin on The Legend of Zelda.

Sly 4. I love these games.

[ParanoiaDragon]

Infamous 1 & 2(you can get a collection that includes Fesitval of Blood)
Uncharted 1-3
Tomb Raider(I was pleasantly surprised out how well it turned out)
Tomb Raider HD Collection(atleast for Legend & Anniversary, but I also like Underworld)
3D Dot Game Heroes
Anarchy Reigns(haven't beaten it, but it's a neat brawler)
Batman Arkham series(especially if you love Kevin Conroy as Batman, but their great either way)
Back to the Future(neat point & click game, they released a physical version)
Ducktales(physical version comes out in November)
The Lego games are all decent fun, nothing super exciting, but neat all the same)
The 2 Bionic Commando digital games, there's 3D game, some people love it, some hate it
The Bio Shock games, people seem to rave about them, the newest one looks neat
Borderlands 1 & 2, get the GOTY versions
Captain America, it got decent ratings, for some reason, I absolutely loved that game
DC Universe Online is kinda cool, I mostly stuch to the single player stuff
Dragon's Crown
Dungeon Seige 3 if you like newer hack n' slash rpg's
Fallout 3 & New Vegas, however if you do EVERYTHING in Fallout 3, the more glitches you can run into, not sure if Vegas has the same problems, also, the games are loooooooooooooooong, I was somewhere over 200 hours when I finished doing almost every little thing in Fallout 3
GI Joe Rise of Cobra, it's a cool Contra'ish game
Green Lantern Rise of the Manhunters, I totally enjoyed this game, I think it got decent reviews
Heavenly Sword
Ico & Shadow of Collosus Collection
Jak & Daxter Collection
The Incredible Hulk, it's a flawed but still fun open world game loosely based on the most recent movie
Lord of the Rings War in the North
Metal Gear Solid 4 & HD Collection
Midway Arcade Origins
Mirror's Edge
Moon Diver
Outland(if you like Castleroids)
Prototype 1 & 2
Rayman Origins
Red Faction 3 & 4(buy em' cheap, as some especially didn't like 4, which I loved)
Resistance(supposed to be a great series, I haven't played them just yet)
Retro City Rampage(an homage to NES games such as Metal Gear, TMNT, Super Mario, Duck Hunt, etc.)
The Sly Cooper games
Sega Collection
Spiderman Shattered Dimensions & Edge of Time, awesome games(Web of Shadows is good too), haven't played Amazing Spiderman yet
Tales of......if you like the Tales games, there's 1 or 2 out, & there's a collection of 2 games that were GC & Wii exclusives

X-men Destiny
Zone of Ender's HD Collection

Hard corps - contra basically

[geise]

Haha!  Yep, still no talk of any Final Fantasy.

[jeffhlewis]

Bayonetta
HOTD: Overkill (worth the PS Move controller purchase in itself)
God of War Collection (if you don't already have GOW 1 and 2)
Persona 4 Arena

[ParanoiaDragon]

I have the PS3 Final Fantasy's, but haven't played them much.  I just don't consider them true Final Fantasy's, but they might be ok. If you pick em up, just do what I did, & get them for under $20.

[TR0N]

I forgot to mention this game,while it's digitally only if you like metroidvania games it's worth checking out.

Guacamelee also supports co-op.

[tggodfrey]

Portal 2
All The GOW
Oblivian
KillZone 3
GT5
Splatterhouse

I liked FFXIII.  It was one of those games I got to the end and never finished but I had fun with what was there and liked the battle system.  It is very linear for the most part.  Only one area I can remember with side activities/quests

Other good RPGs

Fallout 3/ New Vegas
Oblivion / Skyrim
Mass Effect 1-2-3
Ni No Kuni Wraith of the Witch

Heavy Rain is a good exclusive I haven't seen mention yet
3D Dot Game Heroes is fun

Dishonored was a great new IP from last year can be played stealthy or Rambo style

Guacamelee  mentioned above was a great 10ish hour game for the $15 price tag

You already have Last of Us on your post but if your play multi-player games give it a shot the learning curve is high but it is really fun

[Senshi]

Castlevania Lords of Shadow is dumb.   It's quick times, garbage, and lame.

lol whatever. If you like a great story, a deep combo move system and really cool enemies and graphic deaths then you'll like it.

I beat FF XIII.  I hadn't made my way through FF since 7, so I figured I was due.

It was pretty good if you like linear games with high production value.  It wasn't hard, I don't think I ever really lost a fight.  It wasn't good enough for me to ever start the FF XIII-2 I bought for $10 though...

I will probably end up playing through FF 19, if I keep up my current pace.

I agree, I played FF13 and while it was really linear, it was still well done with the production values and an enjoyable story.  Just make sure if you do play it you do some of the side quests along the way, because it's possible to progress through the game too fast and then get stuck being under-leveled near the end of the game.  I've also got 13-2, haven't played it either though

Tales of Graces f is fun too if you like JRPGS in general, and Arkhan mentioned the foo-foo NISA games which I love as well.
