There are few games hat can make you satnd in front of the screen just waiting for that new technology to develop, the game can be mind-blogging once the WWII is in full rage, but at the same time it just keeps you wanting for more...soon you will be looking to play the game with all the great (and not so great) nations...it can be as addictive as when Age Of Empires II came out, but it is much larger in terms of scope and replay value, with the add-on of being ridiculously interesting for those of you with a slight interest in history, politics or weapons, imo only one other game beats it: HoI II
