The game is not comparable to its predecessors. The epochs have been reduced from 15 to 5. The civilizations have been reduced to three, but they differ in terms of gameplay. The world conquest mode is very boring. There are occasional events, but they are often buggy or completely ruin the game. Expect crashes every 30 minutes, which is extremely frustrating. The AI is incompetent in the world conquest mode and fails to advance through the epochs. In my three campaign runs, I always ended up fighting Stone Age units with futuristic units, which feels extremely unchallenging. In the RTS mode, the AI struggles with the Middle East and doesn't know how to properly place its buildings. I have often experienced situations where it simply sends its city buildings into my base or doesn't use them at all. Conclusion: Stay away from this game, even though it says Empire Earth in the title, because it is an absolute punch in the face for every Empire Earth fan.
