empire earth is an addictive game, the campaigns tell tales of heros throughout the ages while a single skirmish on a randonmly generated map with just a single AI set on hard can last hours, the game has basic resources like all of the games of his generation and requires a big civilian population to mine it but the game (like me) does not like the 200 unitcap that almost all on the RTS games of the time had and therefore allow you to have up to 600 unitcap so that you'll never feel like you're rubbing the edges (this can be moded in the scenarion editor to whatever you want) and the scenario editor allows the player to build anything: want a WW1 style map no problem, zombie outbreak? sure thing, the scenario editor is limited to your imagination and allows you to build any type of scenario you want from tribal wars to future wars with mechs and space carriers so, in short it is the most comprehensive RTS game i have ever seen, it has all the options you need to destroy your enemies( even nuke dropping bombers and unke missile firing subs) and a single game here can last hours on end tip: visit gameheaven they have a special web for EE related community made content with missions campaigns and other modpacks for you to enhance and enrich your game
