Well, I'm one of the famous designers for AoE3 Heavengames about two years ago. I'm the creator of AoE3 WW2: Utah Beach and Omaha Beach. But now, after two years, I'm back to start a whole new campaign: The Great War. Here it is, the prequel and hopefully you guys will like it. The official releases are on aoe3.heavengames.com. I'll really appreciate it if you guys review this and on aoe3 heavengames. Thanks!
