Made the switch to Mint recently. Steam says that of 750 games on my account, 748 can run on Linux, and I've had no problems with the dozen or so I've played lately.
The Mount & Blade Warband Persistent World mod servers are like this. All equipment and resources have to be mined, crafted, and used by players, and the only gameplay was player interactions - trade, banditry, war. Amazingly good fun when you're on the right servers with the right people. No idea if its still active or not.
