Team Fortress 2: 1,558 hrs on record
This was the first game I have ever acquired on Steam. I didn’t purchase anything else for a while and just played the hell out of TF2. Although I made short hiatuses to play other games, I always came back to it. Although I don’t agree with many of its content updates and changes, it’s often my go-to game.
Garry’s Mod: 198 hrs on record
What pulled me into Gmod wasn’t the wide arrange of mods and gamemodes, but the ability to make stop-motion films on it. Years before Source Filmmaker officially came out, I would spend hours making short, jaggy and stupid stop motion films. I believe some of them are still up on YouTube. I don’t play much today.
Sid Meier’s Civilization V: 115 hrs on record
It’s Civ 5, what is there to say? The “Just one more turn” feeling enchants me every time I play it yet I seldom complete games I’ve begun. I started taking a break from playing it though, should really come back.
Tabletop Simulator: 83 hrs on record
This is the game that drove me to buy, play and enjoy board games. I bought this while it was on the earliest stage of Early Access. I have created some mods for it, been in touch with the devs and generally playing board games with the friendly community.
Portal 2: 83 hrs on record
Besides replaying P2 multiple times, I was also active in its modding scene (rather, level creation scene). I was fairly active in the P2 modding scene and even contributed to Portal Stories: Mel back in 2011. Unfortunately the level I created isn’t in there.
Borderlands 2: 59 hrs on record
This is how long it took me and a friend I met online to beat Borderlands 2 and some of its DLC. Frankly I thought the game was repetitive and quite dull at certain parts, but my buddy pushed me onwards and I slowly learned to like the game. I didn’t play it very much since we beat it.
