Looking for a game that has the below details?

In detail, I like stealth, daggers, swords, assassination, stealing, running, versatility and speed.

I actually want to combine stealth and speed together. Like I don't really like to always creep up behind people slowly, instead are there games where you can stealth, and where you can move really fast around people and attack them? or does the moving fast around people and attacking only happen in fantasy mmorpgs like mapelstory?

If you don't get it this is what I basically mean, like sometimes there is stealth where I go up slowly to assassinate someone.

And sometimes, I see a group of people, I can like stun them, and then go in and take them down fast, even though I'm exposing myself and there's a chance they'll see me? Instead of like waiting for groups to disperse and quietly taking them all of them.

thanks for your help!

Eh, Thief, Assassin's Creed, Metal Gear? Any o' these sound up your alley?

This is better suited to the GGD Game Recommendation Thread.
