Ok by now you know this is a turned based strategy games where you play cards to attack or heal or buff. Those mechanics are super slick. If everything else was that quality it would be a 9. So good news, the core gameplay is pretty much perfect - although the learning process takes some time.
Interacting with some of marvels most famous super heroes can be a lot of fun. But it does go on a bit! The interactions with them start to drag after a while. Then on top of that there is the other part of the game where you explore the grounds. They are simply not diverse enough to be interesting. I found a few things, and I obviously missed a key moment to activate the cauldron, which I never worked out what to do with that, but at the same time I don't feel like I missed out on the game. The bottom line is that the stuff back at base is pretty bland.
Then there's the lack of polish. There are a number of key moments where there's some bad clipping on character models, and even some poor animations of characters in cut scenes. Which leads onto the final battle. No spoilers, but while all games want to finish with an epic crescendo this over stays its welcome by about half an hour. It just goes on and on, and not in a good way. I did it first time, but it's safe to say that once the credits rolled I had no interest in playing anymore.
This is a great start, and I would be really interested in a sequel, provided it fixes the main problems with this version.
