Its nice to quickly check what game from bundle u already have, but it doesn't work 100% as it should.
From that bundle i didn't have Mad Max and Injustice only.
I got SoM with DLC(not Goty key, bought SP later) and i got Season Pass for B:AK too (from all Batman collection Cdkeys promotion). It didn't show properly. I know there is a problem with steam keys here, different activations and so on, but can it be improved somehow?
I also have sugestion to show u got part of package, for example u got basic game for SoM, so people will know that they got it, and can buy bundle for DLC or hunt them elsewhere.
EDIT: I solved the problem with B:AK Season pass, i added it manually to collection and then it shows on bundle list. Problem here is that it didn't imported from Steam automatically as it should.
