Got Mac?
? Q: Why is Artemis only for Windows computers?
A: I'm most comfortable developing on PCs, but I want everyone to have fun with Artemis. Fans on the forums have been able to play Artemis on Macs using Wineskin. Unix guys have also had luck using Wine 1.3. In the future, I'll keep mobile devices in mind.
JEDIT:
Just saw the rest of the FAQ. 40 bucks?? Get outta here...
