My CE base Isn't too bad either though it does have a couple of scuffs and things here and there, and some scratches on the back, the joining on the back of the frost giant hasn't been put together quite right either, but as a whole the actual piece itself still looks the part!
Where the issue with my collectors set came in is that it didn't have the right figures within the packaging. It originally came with the 3 starter figures, Hulk and 2 Hawkeye's, missing a Captain America entirely, thankfully the issue is now resolved. But as Kitah-san has already recommended If your putting these away for Xmas or Birthday presents it may pay to open up and check if every things correct and in order (thank god it wasn't a Hulk figure missing, that's all I can say).
Hope everyone's enjoying the game though, I know I certainly am!
