To be honest, it gets pretty boring after a while, especially after you finish the main story. There's, of course, a LOT of content post main game, however, it's most of the same thing without many differences besides variations of the same few maps and the same characters you've fought multiple times over at this point.

This is just a grinding 3D game with little to no pay-off besides some in game secrets that you can just find on youtube with a 3 second research.

Legacy characters are not built on, and new characters are shallow with simple and forgetable motivations. Not worth all the money, but if you're a completionist and want to pass time, it becomes a very good game.

I had a lot of fun during this game, but after the first two weeks you just never touch it anymore.
