Videos look awesome, gameplay won't be that great. BF3 had me thinking good things, it's a good game but it didn't match the hype. Same shit happened with GTA4, GTA5 is amazing though.
GTA4 was the building of the engine, GTA5 was a massive content dump.
BF3 was the building of the engine, BF4 is BF3.5 with a shit ton of more content.
