Yes, I have played this game, and have had an enormus amount of fun on it. It has 20 battle levels in a storyline setup, several independent battle maps, A 5 level economic storyline, and a map making program. It works with absolutely no prblem on my eMac 700, or our iMac 500 with OS X.2. When run in OS 9.x its unbelievably slow, and network play dosen't work, even though its supposed to. For example it usually takes the 500 Mhz iMac with X.2 10-14 seconds to load the game when you start it. Our 667 Mhz G4 tower in OS 9.1 takes about 18-20 seconds, and my eMac 700 took 16-18 seconds before I upgraded to OS X.2
Otherwise it is a great game with great replayability (is that even a word?)
Warning- levels 18 and 20 are extremly hard, I was on level 18 for 2 weeks before I figured out how to beat it.
Also- It takes up more then a GB when installed
Peace-
