currently Total War Rome II - 45 hours past last week..

Garry's Mod FTW !

lol what did the first sentence have to do with this?

as for the question, practically any game that you can tell was worked hard on by the devs, even goat simulator, the devs worked hard to make it the joke that it is which makes it funny and has its small portion of fun. on the other hand games like COD, crap simulators, some bundle games that you can tell there was an idea there but the execution of development wasn't well thought out; those are pretty much the only games I don't like/can't really like

The game i have spent the most hours on is Rome Total War (yeap, the first Rome). More than 10 long campaigns fully completed with 8 factions and it's still the only game i have not regretted a moment i spent on it.

As for the GAs, try to enter GAs which last only 1 hour and have less than 500 entries. So far, this tactic has given me 20 games on steamgifts and steamcompanion together.

Currently, Dynasty Warriors 8. I enjoy hack and slash games where you can just roam around and beat up crowds of things. The combos are fun too, as well as the storyline which has 3 routes.

Fallout Series, TES series, CS, CoD..

CSGO!

Dragon Age: Inquisition right now.

Dota 2

Cant quit that shit

KSP

games

Roguelikes, yo

As in genres, or specific games?
I mostly enjoy action/adventure/shooters. Some favorites are Just Cause 2, Tomb Raider 2013, The Elder Scrolls V: Skyrim...

csgo. I suck at it tho.

Silver 4 4lif

Arma series, and I am also playing bf4 since I recently got it.

Binding of Isaac: Rebirth currently. Before the release I wanted to finish other games... Can't do it now.

2300 on CoD MW 2:p

The Binding of Isaac: Rebirth came out a month ago and I already have 140 hours in it. I've got 375 hours in the original Isaac, but luckily Rebirth improved on the original in every possible way for me.

Not on the PC, but the NHL games. From NHL 07 to 14, I wouldn't be surprised if I've spent thousands of hours on the series. Whether or not that trend continues, will depend if the future NHL games warrant going "next-gen" with my consoles.

Right now in my catalog, I have a couple games to beat till I beat every game I have bought. Im on the last couple games and they are all rpgs so I am spending a good amount of time with them. I on fallout 2 and its a really fun game.

Mount & Blade Warband (MP mostly)

Rome TW 2 (MP)

Divinity Original Sin (SP)

Europa Universalis IV (SP)

Total War: SHOGUN 2 (SP)

Just any character fighter RPGs

TES (Skyrim FTW)

Fallout (Fallout 2 FTW)

Dragon's Dogma (Okay, maybe not that one so much)

Dragon Age

Kingdoms of Amalur: Reckoning

Rune Factory

Fantasy Life

Currently, Deponia: The Complete Journey. I won the first game here a few months ago and I absolutely loved it, was just waiting for a decent sale to buy it
