IT's Sim City 3000 unlimited, and a SMAC/AC bundle is very very hard to find. The pack is getting more rare too.

As for the Alien Crossfire game itself, it adds 7 new factions, 3-5 new tech levels, lots of new prodjects, new terrain landmarks, new units and new weapons/abilities and it comes with a Faction Editor. The new features almost change the way the game can be played, it makes Sea Bases incredibly more useful, and makes planet friendly strategies more viable. It's what an expansion should be, a damn near new game, not like 6 units and multiplayer.

The 'Planetary Pack' with both Alpha Centauri and Alien Crossfire is still for sale on Amazon.com -- not very difficult to find. Too bad it's still ~$50 though... you'd think it would have come down a bit.
