Help with finding good ps3 games?

Okay, I'm just going to sum up what I'm looking for.

So basically, I liked the assassin/thief class in mmorpg's. However, I don't like mmorpg's. So I'm looking for a game that reflects the assassin/thief gameplay and style. Like you saw, I had a list of aspects that I derived from those two sites (that doesn't work). Then, when I looked back, I don't think that it's the best way to choose games like that. I think it's better to look at all the aspects as a group, and it'd be easier to choose a game like that.

Instead of looking at a assassin/thief ****in ONE mmorpg, I decided to look at the overall ****of assassin/thieves. I also decided to inclde in other types of "stealth ****s" such as scouts and rangers. Lol, for some reason some mmorpg's don't look at rangers as a stealth **** take for example, maplestory (which I loathe)

So then I looked around and saw that the main attributes of those rpg stealth ****s are speed and stealth. Those wiki sites I looked at (you can find them by googling "assassin character **** also described a lot of the fighting ****of assassin/thieves.

And also, do you think that I should include action games with flashy skills (because a lot of mmorpg's emphasize assassin/thief flashy moves).

So basically, this is what I'm looking for.

Good action games similar to ninja gaiden sigma 2 with all those flashy moves.

Good stealth games. (When I say stealth game, I also mean games like assassin's creed 2 that is considered an action-adventure game but has a lot of stealth in it)

Good rpg's with a good assassin/thief ****

Good "speed" games like Spiderman: Web of Shadows with the nimble and agility in both movement and combat. (This might a be a little tricky because I don't really like games like Mirror's Edge or games like prototype) Mirror's Edge I don't really like because it doesn't emphasize that much combat and it's first-person (I prefer third-person). As for prototype, it honestly takes away the "assassin/thief" feel with so much of its destructive power.

Btw, just one question, are there games that combine stealth AND speed?

And is saboteur considered a stealth game? ( I don't really think so, but I can be wrong )

Lol did I make my range of games way too wide? Seems like a lot of people only look for one specific genre. But since I can't really find any games that actually combine speed and stealth, I might as well go for both types of games.

thanks

I'm pretty sure there's only speed, stealth, and combat that I'm looking for in assassin/thief ****s because all those other attributes can't really constitute a game. If you can, take a look at the wiki sites, they may help you a lot.

Sorry about not putting it in the game recommendation section, but it's just that I tend to type way too much and it takes days to get an answer.
