To reduce redundancy here are some projects already being made (I'll add links in a bit they are on Lemmy if you search Tux. Except Conker's Dev I know them) but if you still want to make a project in those genres then be my guest:

• 3 people are working on a Tux Smash-like

• SuperTuxKart Team is making their next iteration of the game to be overhauled (They have a name for it but forgot what it was called)

• Know a developer working on a Tux Conker-like game

For a couple personal suggestions of games that people would love. It will be cool if we get any of these. I'll put in my vote as well:

• A New Tux 2D Platformer Game
• A Farming Game like Stardew Valley
• A 3D Platformer Game with support for up to 8 players with local couch co-op and online co-op (With a Mario Maker to make it complete)
• A Brand New Tux Party Game
• A 4X Grand Strategy Civilization Game
• A Turn-Based Final Fantasy-like Game
• A Horror Game
• An RTS Game
