People say that about every game they don't like tho, Tekken 7 and SC6 and SFV also have very if not more tedious tasks you have to do to unlock costumes as well, DOA6 has at least made it by now a total cake walk online and offline to unlock costume parts now

There is nothing tedious to unlock in SC6. I had all the unlocking parts in cas within a month. There isn't much to unlock in SC6. Take that game off that list. Also we don't know if that will stay and also the system is still not good as it is random and you have to go to Arcade and etc. to get patterns you want. Even after that you need coins to unlock the costume.

It's not very good even with the increase of patterns that may not stay around. Someone did the math and said you need 2 million coins to unlock everything. That is nuts!

They planned to update it to make it character specific tho and it's not bad imo, it took me two weeks but I unlocked everything. Plus you get coins for doing almost everything and you can always just buy the things you want only, like I haven't bought anything for characters I don't use
