Civilization IV

Civilization IV is a historical-simulation game where players develop factions throughout the known history of mankind. Players build cities which produce the structures and units of the game and are the source of income and technological growth. As time progresses factions will discover new technologies which allow them to improve their cities and build more things. Each faction is led by at least one historical figure famous in history. Diplomatic relations between different factions are represented by interactions between these historical avatars. Everything is cool until someone gets stupid and destroys my work boats.

Solutions & Issues
Widescreen Solution & Issues:

Game is actually slightly Vert- and Hor+ for widescreen but you can zoom in and out which makes the game extremely playable in widescreen.

Eyefinity / Surround Specific Solution & Issues:

Surround support out of the box (at least with the latest patch).
However, it's -vert surround, which let's you actually see less and making the game despite zoom nearly unplayable.

But with a small tweak you can play like it was meant to be played.
You need to fix the globe-view and city-view both in two different files.
Make a backup before editing. :)
