I had some high hopes for avengers initially. If they had managed to replicate the gameplay progression of say Destiny or Division 2 in a way that made the game feel much more appealing than it was, I figure it would've been more successful. It clearly suffered from the vanilla syndrome of being overly repetitive and having zero endgame.
GoTG, while having some more positive reviews and feedback, was such a huge miss at having some kind of online co-op with the team itself rather than only being able to command the other characters.
Oh well.
