Mindustry, sort of like factorio but open source and free on itch. Although you can also buy it on steam

I go back to Battle for Wesnoth a few times a year. There are many new scenarios over the recent years.

Right now I’m really getting into old school games or games that have the old school look. Here’s a few which have native Linux support:

• Stardew Valley
• Broforce
• Carrion
• Dusk
• FTL: Faster Than Light
• Huntdown

Aside from some of the things mentioned here, Death Trash is a pretty neat indev rpg.

I really like Golf With Your Friends.

Mount & Blade Warband is fantastic and I highly recommend it if you haven’t played it.

Unrailed! is a neat little coop game to play with friends. If you buy this one on Steam you can use remote play together so only one person in your group needs to buy it.

Ultimate Chicken Horse is fun for a while with friends. Same deal with remote play together with this game.

Both Hotline Miami games are really fun.

Don’t know about them being the best, but I’ve been playing Valheim and Shadow Tactics: Blades of the Shogun and having a good time with both.

The Talos Principle must be mentioned here. It was the first major game to provide Vulkan support, running just incredibly well.

And of course, Minecraft.

I know you are specifically asking for natives, but with the awesome work Valve has put into proton so many games play well with linux now!
