Ha, I couldn't resist it... I bought Civ 4 (for the third time)
First, I bought the vanilla version many years ago at a good price.
The expansions came, but I couldn't find them in any place. Mexico is not the best place to buy computer videogames.
I could boought it when the Civ 4 complete edition came, but it was really expensive. It was my own birthday present, so it was worth it. When the last patch came, the one that lets play without the disc, I became the happiest player on earth.
After that, they published Civ4 colonization, but it didn't pick my interest. At least, I didn't want to make all the effort to play a "game similar to Civ4 that is not Civ4".
But now in Steam... 7.5 dollars... all the package... and I can play it on MAC ( I have plans to buy an IMac) And it includes Colonization as a separate game, so it won't interfere with my current Civ4 instalation... SOLD!!!!
But it seems Colonization is not available on MAC, but who cares...
