These are recommended games that may not get mainstream attention, but deserve it in my opinion.

Hyper Light Drifter - A top-down sword/gun adventure with a good soundtrack, atmosphere, and challenge

Mechwarrior: Online - A mech game with a nice level of depth and customization without being too complicated. Although it released over a decade ago, it is still supported to this day.

Inscryption - A card-based game where you just need to go in blind

Laika: Aged Through Blood - Trials with guns and a story. The challenge may turn some away, but the story and art makes you think about it long after you put it down. It's brutal in more ways than one.

Pyre - It's sort of a new sport set in a post-apocalyptic world. Play this when you want a change of pace from all the normal game genres.

World of Horror - A retro text-based rpg horror game you can jump in and out of pretty easily. Each playthrough is different and customizable, and lasts an hour or so depending on how you play.

Dawn of War II - For when you like RTS games, but not base-building.

FTL: Faster Than Light - Manage your starship's systems and crew to fight your way through the galaxy

Hi-Fi Rush - An rhythm action game that has the style, story, and polish that gave me nostalgia for the good ole days when games were just fun without trying too hard to take up all of your time. And the soundtrack rocks too.

UFO 50 - A collection of 50 games made by a fictional game development company in the 80's. There's something for everyone here. These are not mini-games either - they're full games.
