1. The Mac Gamer's Ledge <http://www.macledge.com/> - This site is awesome. Good reviews of many of the latest games (very well done reviews), as well as up-to-date gaming news. These guys are awesome. 2. Ambrosia Software - they also have some good resources for gamers, not to mention the best mac shareware games available.
3. The Unofficial Mac X-Wing page <http://life.bio.sunysb.edu/mcb/hunter/xwing.html> This place has great tips for getting through some of the tough levels. Also has pointers to various Mac-specific updaters and extensions for this most incredibly awesome Mac game of all time.
Anybody planning on getting X-Wing vs. TIE fighter this Christmas? I sure hope to get it around then or shortly later. That would make for an AWESOME VMUGM meeting :)
