1. RimWorld - I don’t think I’ve ever seen a game care so much about making the player feel like part of the story; just all around amazing. Damn near everything is configurable and for anything that isn’t the modding community probably has a fix for (and then some).
2. Terraria - Certainly has its quirks and annoyances, but I like that it has sandbox elements to be creative and do whatever, but also always feels like the game has an objective to work towards. I’ve probably played though at least half a dozen times between solo runs and multiplayer games with friends/ family and I just keep coming back to it.
3. Stardew valley - it’s just cozy with a slight hit of nostalgia. I have childhood memories of staying up entirely too late monopolizing the TV/ GameCube playing Harvest Moon and this scratches the same itch. Beyond that you can feel the love and attention to detail that the dev has poured into the game. Plus the skill ceiling is pretty low, so even my non-gamer friends/ family can play and have a good time.

Honorable mentions:

• Factorio
• Slay the Spire
• FTL

Yeah, probably. There is a village building/ upgrading component, but it doesn’t have much of an impact on gameplay. It does get pretty tedious, especially if you’re well versed in strategy. I mostly just figured I’d throw it out as a more casual one-shot to pick up on the cheap.

Infested Planet

RTS. Kind of reminds me of the ground comabt from Star Wars Empire at War crossed with Starship Troopers. Command a squad of space marines tasked with battling an overwhelming alien horde. Pretty fun campaign (if a bit of a predictable story), plus an endless mode. Not exceedingly difficult, but definitely challenging enough to make you think tactically and keep you on your strategic toes. Somewhat limited replayability makes the sticker price hard to recommend (unless your bread and butter is RTS), but it regularly goes on sale for less than $5, which it is absolutely worth!

Ara Fell

The whole things just a massive labor of love from a relatively small indy studio. At one point it was an RPG Maker game that was delightfully well polished in terms of story, art, and environment. After the devs got tired to rpg maker limitations, they ported the whole thing to Unity and re-released it as a free Enhanced Edition update. Childhood me played the shit out of GBA Harry Potter and the Prisoner of Azkaban and it very much scratches that JRPG itch.

Sproggiwood

Rouge like turn based dungeon crawler. Certainly not new by any means, but still a pretty decent little dungeon crawler. The art is cute and the game is pretty simple to pick up, which makes it perfect for more casual play. That said if you’re a completionist, it can get a bit repetitive, but nothing too hair-pulling. Probably not worth the full sticker price, but historic sales have knocked it down to $1.49, which is a nice balance between cheap and fun (took me about 28 hours to 100%).

Alina of the Arena

Hex based rouge like deck builder. If we’re taking indy gems, this one’s probably a nice Amethyst. Not quite the most polished (the game kind of just throws you in without much of a tutorial and the story’s pretty bare bones), but overall a solid B. If Slay the Spire and Into the Breach are your jams it’ll be right up your alley.
