For me, it's the campaign that lacks depth. The multiplayer is the standard multiplayer and it's great. But the campaign is not very good. Two of the four acts are open world which could be a good thing if it wasn't for the fact that your choices in the game mean absolutely nothing. The end of the game choice you make is probably one of the worst decisions that the Coalition has done for the series. They now have to make a statement saying which one is cannon or make it like Mass Effect and be able to import your save files with your choices.
