BattleBit Remastered is the current game climbing the ranks on Steam, made by a tiny team of only 3 people it has regularly seen tens of thousands of players. It works on Steam Deck and desktop Linux but the anti-cheat may turn into a big problem.
It’s a shame but an overall positive for the community I would say.
Sure, it’s a big issue that it breaks compatibility with Linux, but unfortunately it’s a quite small userbase that will be affected vs the userbase that will benefit from this.
The ideal world would see the anticheat software developers providing compatibility with Linux, but again, I doubt it’s high on the priority list with such a smaller userbase in comparison.
