Definitely sounds like something worth checking out one of these days. And hell, if I ever feel like dropping Minecraft and picking up its open source equivalent Luanti, it sounds like it would run on Haiku.
I once tried installing OpenIndiana as my daily driver just to be different but it didn't like my graphics card.
@cowanon@Humpleupagus i run it on bare metal (thinkpad) as a (primarily) writing and fucking around machine. The UI is surprisingly advanced for its heritage, it's lightning fast, runs lots o' open apps (libreoffice, firefox, etc.) plus its own weird world of BeOS/Haiku apps. The only downside is no security (no login prompt, even), though apparently, there's an encrypted volume setup that works for it if you put in a little extra effort.
Totally worth checking out in a VM, but be careful, you may fall in love with the weirdness.
When it was still called Minetest I played with the MineClone modpack for a few months. This was when a Minecraft update refused to work on my computer anymore, but it started working again for me with its next update, and coincidentally Minetest stopped working.
It's not too bad. I'm sure mimecraft had infinitely more mods, but if you don't want to pay Microsoft for a game the base of which can be coded in a few lines of python, it's free and does its job.
