Comparing it to other games is stupid. The only real comparison can be made with previous AvP titles.
AvP3 (yes, it's AvP THREE) is a decent game with a high fun factor for fans of the franchise(s), but unfortunately, it's not as good as its predecessors. Patches and DLC may upgrade the game somewhat, however, The Legends (AvP1 & 2) are still unbeaten.
