Sauna2000 (it's not out yet, but there are some demos floating around).

Squirrel stapler

Cruelty Squad - depends on the kinda person you are. If you're super open-minded about game presentation then I'd tell you to go into it blind. If not, then I'll happily try to sell you on it. If it helps, the game looks the way that it does because of how fucking confident it is in itself; and that confidence is fully justified. Give it time, even if the first level doesn't hook you, give it time because in my experience it will eventually hook you and reel you in and leave you thinking it's one of the best games of all time.

Undertale

Hypnospace Outlaw

Jet Set Radio, Jet Set Radio Future, Bomb Rush Cyberfunk. Give the first two a try, and if you don't like either one, skip BRC; it's a spiritual successor to JSRF and if you didn't like JSRF then you probably won't like BRC.

Hylics. If you liked that and wanted more, Hylics 2. Hylics 2 actually does something throughout the game that I've only ever seen as a gimmick in other games. It's really cool and it'll probably catch you off-guard every time it does it.

Katamari Damacy. If you liked that, there's also We <3 Katamari.

Myst. The newest version has VR support. If you liked that, the recent Riven remaster also has VR support.

S C O R N (if you like Myst, give it a try. It feels very myst-like)

Hrot (boomer shooter, but if you like boomer shooters then you should give it a go).

If you're at a place in your life where you're trying to still find yourself: Night in the Woods. Especially if you're a furry. This game is really fucking good. It'll make you laugh. It'll make you cry. It'll make you miss home but also be glad you aren't there anymore. It'll make you question your place in life and who you are. Also, you can interact with things multiple times, make sure you don't miss out on dialogue, you'll regret it.

STALKER: Shadow of Chernobyl - This is hard to go into blind because it's buggy as fuck and most people recommend some form of community patch even for your first playthrough. That said, play it on the highest difficulty. It's unironically more fun once you get used to it. If it's too hard though, don't be fooled into thinking that dropping the difficulty will make it easier, the hardest difficulty is special (you can only take a few hits, but the same is true for most enemies), and dropping it down will result in enemy difficulty scaling becoming more traditional (buffing health and damage).

Portal (and Portal 2).

Bugsnax.

If I can throw in a movie too:

Willy's Wonderland. It's a Nicolas Cage movie and that's all I'll tell you. DO NOT LOOK UP THE TRAILER. I wouldn't have watched it if I hadn't seen the trailer, but the trailer also has huge spoilers. I'm not a huge movie person and I had to watch it after seeing the trailer, but again the trailer has spoilers. It is on my top-10 movies list now.
