I just hope they still have options to easily unlock at least one alternate costume via arcade mode, and buying all of stuff if we want OR via unlocking the krypt. I like having different ways of getting costumes, cosmetic colors etc but I really hope we have a 100% FREE color pallette to play around with. This was something they didn't do in Injustice 2, I can understand why since DC aren't their characters per-se but MK characters are in regards to creation.
In other words, in I2 I couldn't have a white Superman outfit with blood red heat vision eyes and say orange S with black trim around it. I hope they consider allowing a free color option to change the armor, costume colors etc how we want as many pieces as possible. Like MK Armageddon's KAK or WWE KAK. If you guys know what I mean. Essentially, what I want personally is a system that allows us the freedom to as unique, detailed as possible just short of a PC mod in terms of colors and outfits the game will offer. So if someone wants a hot pink Scorpion, glowing green eyes, let them or an orange Sub-Zero with glowing white eyes, let them. Why not?
