Totally badass game.

Far Cry 3

Duno why but I rly liked it so much... Didnt happen in long time

Skyrim because I killed Alduin :)

Team Fortress 2: anytime I play Pyro and I get like 3-4 Soldiers trying to kill me with their little rockets :3

Freedom Fighters.

Metal Gear Rising: Revengeance. Rules of Nature is all I have to say. But don't look it up on Youtube, it'll ruin the surprise.

Devil May Cry.

Tron evolution it may be old but was one of the best games I have played only downside was I had to use GFWL.

I felt very involved in Final Fantasy VIII, started to feel attached to the characters, to feel I was "one of them" :-P

The operation in Deling City at the end of Disc 1 is epic.

DarkSiders II when you turn into Reaper Form and beat the crap out of the bosses.

Tribes Vengeance. The game wasn't all that memorable overall, but I have a great memory of jetpacking to the top of a fairly high cliff with a couple of enemies in aircraft chasing me, whipping out my laser rifle and sniping one of the pilots out of his plane, diving off the cliff as his plane began plummeting to the ground, catching his plane on the way down and jumping in it, then shooting down his buddy with it. It felt like something out of a Bond movie.

Civ III/IV. There's nothing quite as satisfying as seeing a knight on horseback get killed by a bomber.

That said, there's nothing so annoying as having a tank killed by a dude with a pointy stick.

Fallout: New Vegas the Dead Money DLC.

When I stepped out of that bunker again, seeing sunlight for the first time after like forever, I felt like the baddest mofo ever.

Deus Ex (the original) and Deus Ex: Human Revolution.

Because both can make you feel awesome in different playstyles. Best moments in the first game are when careful exploring of the game world gives you an explosive way to completely bypass two fairly tough boss fights.

Saints row 3

because you're the best around and nothing's gonna ever keep you down

For me it's Binding of Isaac. I felt like a boss when I first beat mom :)

There is obviously Skyrim where you play the mighty Dragonborn. I wish there was more interaction with Paarthurnax, I really like him.
GTA IV . In the end you finally get to live the american dream (or do you? I ended up chasing all the pigeons like a madman xD)

Rogue Squadron 3D

Dark Souls, that game gives so much satisfaction after killing bosses that u cant imagine that. Very Frustrating game but so enjoyable on the other hand...

Borderlands 2

Serious Sam is totally baddas.

Blood dragon! Almost at end

Dark souls >:D
It's one of the only games in which I'm really satisfied after defeating each boss, instead of being "k, next"

mass effect 1 2 and 3 :P super story and newer one deus ex
