Inscryption (-60%, $8) is fun if you are looking for an easier Slay the Spire (roguelite deck builder) with escape-room-style meta-puzzles
Doom Eternal (-75%, $10) blazes a new trail for the stale FPS genre and is a great game to use to learn flickstick
Into the Breach (-50%, $7.50) I LOVE this game but also find it really really stressful because you have to play perfectly in order to have a chance against the final boss. Every turn is basically like solving one of those chess puzzles.
Games I'll be picking up:
CrossCode (-70%, $6) is some kind of hexbear favorite but I've never played it
Wolfenstein II: The New Colossus (-85%, $6) - I really loved the first one as a modernized Half-Life 2, although have heard this one is not quite as good
Sonic Mania (-75%, $5) - this is apparently a retro-styled sonic game made in the modern era; I've never played a sonic game before but loved Pizza Tower, so looking forward to this
Note that the CrossCode DLC A New Home on itch io did not come with the bundle and is not on sale and if you want it it would probably be cheaper to just re-buy the game and DLC on steam.
