What is....?

Sleeping Dogs - one of the best games ever IMO.

Just Cause 2. There's lots of fun to be had in this game, but for some reason, I seem to be the only one to be crazy about this game. :(

It depends, what sort of games do you like?

I must say the original Hotline Miami is one of my favorite games ever. Beaten it four times and trying to get the platinum trophy on PS3 at the moment.

Soul Nomad and the World Eaters (PS2)
The devs have also made several other games, mostly on Sony systems, their most well know games are the Disgaea series.

In Terraria you will always find what to do :D Especially when playing with a friend on your own created server

castlevania symphony of the night

really? Fallout 2. not 3 or NV.

Deus Ex (first one and Human Revolution)
Dishonored

As the clown is too distracted stocking up on caffeine and meth to fuel his future gaming spree, it goes to me to suggest The Witcher 3

Return to Castle Wolfenstein / Wolfenstein: Enemy territory

Kirby

Dick tracy for DOS and (S)NES

Dragon Age: Origins!!

Try Hyperdimension Neptunia ... that game has solid 50h worth of content ( if you wana do everything make that 100+ ) ... that should keep you busy for awhile .

destiny..? people hate it & still go back to play for random loot

Star Wars: Knights of the Old Republic 1 and 2, not to be confused with the similarly-named online game. There are tons of mods, including graphic-enhancement mods, and the story and gameplay changes depending on you choices. The original Deus Ex and Des Ex: Human Revolution are similar, and worth playing, in this regard.

I personally suggest either Far Cry 3 or 4. I've been enjoying 3 a lot recently.

Bad Rats

If you want a lot to do, give Ultima 7 a shot! Lots to do, good writing, a more "living" world than pretty much any other open world CRPG, it all adds up to one of the best games of all time.

My personal favorite is Baldur's Gate 2. Recently, I loved The Order, despite what the critic said

My all time favorite is Fallout 3. I never liked TES series, but this one... My most played game ever, back in 2008 i spend over 250+ hours on it. My hype for this E3 is over 9000 because of possible new Fallout announce, don't let me down Bethesda

I'd suggest Mass Effect but I see you already own ME2. Still, I recommend starting with the first one.

Goldeneye 64 one of the best games i had so much single player and multiplayer fun with

Go play GTA V and screw around or something.

Dark Souls all the way. Although right now I'm sinking my teeth into Pillars of Eternity, which I enjoy immensely. Witcher 3 is next :3
