A neat and unique strategy game from the makers of excellent Supremacy, Global Effect puts a new spin on the "conquer-thy-neighbor" genre by focusing on the environmental impact of your decisions. For instance, let loose a nuke or two and observe the result on grasslands, or grow more trees and reap the benefit.
It is also among the first real-time games that offer multiplayer support, although the confusing interface detracts a little from the fun.

A really great game full of ideas that ended-up delivering absolutely no cohesive explanation of how to play it. I did own it back in the day.
No comment nor review for this game at the moment.
