Black Mesa

A remake of the original Half-Life. Never played the original Half-Life but this feels a lot like HL2 so I'll assume they did it justice. A fairly long campaign filled with combat and physics puzzles. The base game was made back when video games actually had soul and this remake feels like one of the best games I've played in years.

Code Vein

Anime Dark Souls. Not as punishing as Dark Souls, and quite a bit more straightforward with less getting lost in huge mazelike structures. Allows you to partner with an NPC who will help you fight through enemies and can heal and die just like you. Has a varied cast of likable characters that are much more involved with the story than Dark Souls' solo protagonists.

My Time at Portia

Like Stardew Valley, but you're a carpenter instead of a gardener, and the game is 3D instead of 2D. Collect resources to complete work orders for people around town. Get asked to help with town projects and watch the town expand and advance with new technologies. Has a dedicated storyline that plays out involving building, combat, and a bit of exploration.

Papers Please

You play as a border guard in charge of checking passports of people coming into the country. As the nation starts tightening down on security you're given an increasingly difficult number of documents to ask and check for, along with having to deal with any terrorist threats than come up. Great main menu music.

Project Wingman

A game made by fans of the Ace Combat series. Fun aerial combat and a compelling story. Feels just like playing an actual Ace Combat game.

Wandersong

A story about being a hero. Great, great story with a great moral. Filled with platforming and puzzles all based around singing and music. Bit of a silly, cartoony game, but I would personally consider it a must-play and I would highly recommend giving it a chance.
