An unique set of actively developed open source games ported to PowerPC Macs running Leopard (with some minor [untested] support for Tiger). These only had binary Intel builds, so after some heavy treatment, they fit right at home. Xonotic - 0.8.2 http://www.xonotic.org/ An arena first-person shooter based on Nexuiz, with multiplayer support. (Client and Server included) The current version is pretty GPU heavy, so this will work best with a G4 or G5 with a higher end card. http://fox.furcode.co/macOS/PPCCollection/games/xonotic-0.8.2-ppc-darwin.zip SHA1=50d05c030b9f1548d8e70c148df0dff569b4e6e5 Teeworlds - 0.6.4 https://www.teeworlds.com/ 2D multiplayer side-scrolling shooting game based around cartoon physics. (Client and Server included) Actually works quite nicely on even slower machines, and is buttery smooth on a Ti PowerBook G4! http://fox.furcode.co/macOS/PPCCollection/games/teeworlds-0.6.4-ppc-darwin.zip SHA1=dbfaeb54efb96f62c80ee3783e03b4039f61f006 Colossal Cave Adventure - 2.5 https://gitlab.com/esr/open-adventure Fan of the original text-based adventure game? This is for you! This was already released as part of another thread, but it may as well be thrown in here. http://fox.furcode.co/macOS/PPCCollection/games/openadventure-2.5-ppc-darwin.zip SHA1=ae10f0b12df16e03b3e1464fbef2dedf12184e69 This is a project I'm actively working on, so there are more games to come (and posted to this thread over time)!
