E3 2011: Playdom's City of Might goes to war with Zynga's Empires & Allies this summer

Don't they say imitation is the sincerest form of flattery? I hope Zynga will feel mighty flattered then, as Playdom unveiled a new Facebook game at E3 this year - City of Might. During my limited demo of the game (I wasn't actually allowed to play, but rather was shown a scripted series of events), I learned that City of Might combines the city-building elements of City of Wonder with resource management and player-vs-player combat. Instantly, we're left with comparisons to Zynga's Empires & Allies which just launched days ago.

For City of Might, you'll need to collect resources to build more units, and can then use those units to plan and execute invasion strategies on other players. While combat is a bit interactive, it's mostly cinematic, and you'll only be able to place your units on the enemies' maps and then add more units mid-battle if your troops wind up defeated. From what I saw, it appeared that the rest of battle was automated, as each side shows their damage as small numbers that float rapidly up from the unit or building in question.
