I will add more blue hearts

I recommend Strange Horticulture

I just wonder how you got so many games, but no Factorio :O

Danganronpa or hexcells really got me.
They are very different btw.

Well, I have to say No Man's Sky has progressed very well since its horrible release. Currently enjoying it on GOG, but it is on Steam as well (:

Grim Dawn, if you like Diablo)

Old school FPShoota Prodeus
Won it, played it, enjoyed it -__-

Idk what kind of games u looking for but i recommend something like hunt showdown or project warlock 2 if u like old school shotter

you are already on my whitelist 🦄 best game is RDR2

If you are into JRPGs i recommend NieR Replicant and NieR:Automata. i had a lot of fun with these.

Monster train, super fun card battler with infinite replayability!

I recommend a game with unique atmosphere called Penk Park

One of my favorite indie games, that's not as well known as I wish it would be:

I'd recommend Postal 2, if you haven't played it already. Not Postal 3, not Postal 4 - and not Postal 1, just the #2. With or without its Apocalypse weekend DLC, which IMO gets a bit confusing

I don't usually go for 'simulator' games, but Tabletop Simulator is pretty good

I've made a ton of mods for it too:

Paying attention to one's taste is important, I guess, but TOEM can be a jewel which is not famous but is worthwhile to enjoy.

I can see you have Yakuza 0 in your library. Definitely give that one a try!

I highly recommend playing Pyre. Great story, art and soundtrack.

The Walking Dead (videogame series)

Wartales is the Shiz Nizz

Since you have Deus Ex: Mankind Divided in your library, I'm gonna go with that one...
Although Deus Ex: Human Revolution - Director's Cut is probably one of the best games ever made!

Outer Wilds is a unique, wonderful game, and I recommend it very highly, but I think most people are aware of it.

Heat Signature doesn't get the recognition it deserves. It is so much fun, and has staggering replay value.

ISLANDERS also deserves more love. It's really something special, it's so meditative and yet if you care about playing strategically, its mechanics are extremely well crafted and satisfying.

All 3 of them aren't in your library, so hopefully one will tickle your fancy 😁

If you're into extremely hard puzzle platformers, I would gladly recommend this hidden gem called La-Mulana.
Thank you for the opportunity 💙

Days Gone - really enjoyable zombie open-world game. Amazing scenery of Oregon, customizable bike that fun to drive, challenging zombie hordes, good story.
I see you have Plague Tale in your library. Wonderful game.
