Both of the IM games have not been that great didn't even finish either of them because they were boring.
Really hoping for an Avenger game that really makes each character completely unique with his/her powerset. Do really like RPG leveling up options so you can take your characters down a different path depending on what you want out of them.
As far as the MUA1 vs. MUA2 debate goes, MUA1 was better for RPG elements, the length and having some other fun elements in it. MUA2 the heroes powers were pretty awesome and the graphics fantastic but it was way too short and why they stripped the RPG down was a mystery to me. Also the whole story at the end was terrible with Fury and the virus thing that led to fighting Fury at the end, not good.
Yeah I had mixed feelings about MUA2.. Just felt it could of been a lot more if they improved on the rpg elements.. But at the same time the gameplay and powers were amazing.. The heroes really felt powerful where that so much wasn't the case in the 1st game.. But the story in 1 was so much better... And I can honestly say in future installments we need more than 24 heroes I mean that's all their is to it and more than just 1 alternate costume.. but needless to say, both games had their strengths and weaknesses..
