I've put a lot of my time into Nuclear Throne. Like, whenever what I'm doing isn't satisfying I launch NT and go for a run, repeat until I die stupidly on loop and can't be arsed to get a run as good, then I quit.
Dishonored is probably my favorite singleplayer 3D game I've known. Love almost everything except for a game-design detail of the fact that it gives you a fun way of playing and encourage doing the unfun way.
Some games that I don't play much anymore but will forever be within my heart:
I've bought Factorio this summer, and played for hours and hours and hours with friends. The community, if you ever see it, ain't fucking joking about how addictive it is. Also, it's an insanely finished game for an early access, and just an incredible thing as a product.
I've enjoyed parts of Borderlands 2 that I've played with mostly Tumbolisu. Especially in the starting areas, level and visual design is really inspiring and it's refreshing to start the game anew... the beginning gives off a much nicer impression of the game than playing the rest, especially alone.
Duck Game. It's really a nice, the amount and quality of small gameplay details is wonderful.
Terraria, I still remember the times we've played with Tumbolisu, killohurtz, zahn and whoever else. Good
theres a lot of games i like and i've listed a lot sure blah whatever
