I can't get it to work no matter what I try. I've tried it on both a Windows 7 and an XP machine (with ATI cards).. tried restarts, compatibility, running as admin, etc

Here's a solution to help you start the game in windows 10 (perhaps 11 too). Download the PhysX-9.13.0604 legacy driver. Just Google it because I doubt I can put links here. Nvidia hosts the file. Install and the game should launch.

Game kept crashing everytime I started it but now it works, I had to Install this Physics Driver for my ATI Card. http://www.nvidia.com/object/physx-9.13.0604-legacy-driver.html EDIT: No Mouse Cursor Fix and How to Edit Resolution or Game Crashing Fix! I created some guides on fixing these issues. Check the Guides section Tab above to see them all....

Just wondering if anyone knows why this game isn't showing in the game store?

After the abandonment of the game by the developers and distributor, and that it has been removed from the steam store, I have the doubt if this game is already classified as abandonware and in that case, it would be nice to know if the rights could be obtained to repair the game and make it fully operational again within the store..., I wouldn't mind taking over said product, since it's a very good classic game and it's a shame that it's lost in limbo....
