I really got into their racing game,
Redline. Fortunately, one forum member took the time to create a patch to get it to run in Mavericks which also works in El Capitan! I have not tried it in Sierra yet though.
I actually just played Redline yesterday. Works well with the Logitech G27 and the old 10.6 Force Feedback kext installed into 10.11.6. There were so many user created tracks and cars you could add into the game that it was quite fun. Unfortunately, the toolbox app to import models and create tracks that Ambrosia supplied with the game only works on older PPC Macs, but I still have a PowerMac G5 Quad sitting around if I really wanted to toy with it again.
I also really liked Aquaria and Darwinia. I would love to see Aquaria on the AppleTV.
