NOT compatible with Windows 7 Profession and NVIDIA GForce graphics

Summary: Civ III would not display properly (or run at all) on my Alienware gaming laptop. Definitely a graphics conflict. I think the graphics are too old and too low resolution for this machine. CIV IV will run, but the audio hisses and locks the machine. The ONLY thing that has ever caused this machine to lock up. These are not games for a high end, high res gaming computer. Ironically, they probably would run better on an older -- or just lower resolution -- machine.
Summary: This used to be a great series of games. However since STEAM has gotten involved, you cannot play off line, I cannot take my game with me in the car on long trips when the wife drives, no creative cheat codes, and if STEAM does not condescend to allow you to access YOUR game, you are out of luck. The game seems "buggier" with STEAM, The only reason it does not get one star, is that I did it to myself, I ordered it, I downloaded it and regrettably I paid for it.
Summary: I LOVE Civ 4, always have. I bought the mac download version a while ago but it suddenly became glitchy - all the links and buttons began to say FUNCTION_GAMEPLAY_KEY instead and I simply couldn't continue. Tried to re-download it but it didn't help.
Limited Compatibility - Understand before purchasing

Summary: This add on for Civ 4 only works with the Steam purchased version of Civ 4. I purchased the Mac download of the Civ 4 game from Amazon and purchased this add on. The add on will not work unless you 1) Have or create a Steam account and 2) buy the Steam version of Civ 4 ($19.99) as of this writing. This should be explained better in the product description. Two stars not for the game quality, but for the distribution restrictions/requirements.
