Knowing my addition to games I will purchase them all.
My prediction, however, is that Battlefield will have the biggest following due to the combination of crowds that loved Battlefield2 (and still play it) and the group that moved to 2142 and still play it...this one is likely to give both fan bases what they want. My biggest draw to the game was the immense virtual battlefields that one could explore most mulitplayer games limit you to a very small football field like space while this game gave you a site the size of 1/3 of Dayton to play in. I wonder if they will make a mod for this one that was as much fun as Titan mode in 2142, man did I love that mod. I have not done much research into the game but at this time my hope is that they reinstated the flight sim controls to the flying vehicles.
I love AvP because of the three classes (mine was always the high speed wall-walking melee of an alien) however I fear the lack of balance that really ruined the original MP deathmatch such as the alien pounce or the predator's homing disc will still exist. Of course there were the other multi game modes where you could have fun. There was gauntlet mode consisting of rounds of aliens against you and your friends (much like CoD:W@W zombie mod). The other one was a king of the kill mode that spawned one predator against a team of marines with the first person to kill the pred becoming that class.
