Ron Gilbert is a name most in the game industry will know from the likes of Thimbleweed Park, and earlier works like The Cave while at Double Fine and they were even the producer on my all-time favourite RTS Total Annihilation. More than that, Gilbert was also the creator of the classic Monkey Island and it appears they're now attempting to switch to Linux.
Terrible Toybox, the actual team behind Thimbleweed Park are working on a new game and game engine too. They released Delores: A Thimbleweed Park Mini-Adventure in May 2020, as a small standalone title that acts as a prototype for their newer game engine. They even put up the source code for the Delores game on GitHub, although it's not under an open source license. It doesn't support Linux yet but that appears to be planned.
So what's the fuss about? They're switching their development flow to Linux and they've started blogging about the adventure too with a first post about their new hardware a few days ago. Seems they've settled on a Dell XPS 13 with Ubuntu Budgie. The question is: why are they doing it? As they said in the post:
My goal is to see how far I can get developing my new game on directly on Linux and not the Mac (I haven't developed on Windows in years). Can I ditch the Mac and go 100% Linux?
For working on the "game", this shouldn't be a problem once the engine runs on Linux. The few custom tools I use (Wimpy, for example) and all built from the same code the engine is, so once it's working under Linux, they should compile as well.
It's quite interesting to see more developers try out Linux, although not too surprising with how Apple is now again moving CPU architecture. Not just that though, as Apple have been getting more hostile for indie developers, with all sorts of extras being needed now and that's on top of the "Apple tax" that forces you onto their hardware. Gilbert mentioned this as well, with Apple being 'more paranoid and authoritarian' as time goes on.
Since their initial blog post it seems it went mostly okay, and they're continuing to learn and find the software they want. Will be fun to see how it all goes. Good luck, we're here if you need us Mr Gilbert and our Forum is always open. We're always happy to help game developers on Linux.
