VF5FS had the most awesome customization ever, it made the game 10 times more interesting. I wasn't a fan of TTT2's though, no matter what items/hair you used the character usually ended up ugly... SC5 was somewhere between the two.
I think if TN does it it'll definitely be up there with VF5FS. We're kind of halfway there in vanilla DOA5, I think they were testing the waters with all those palette swaps (cheerleaders, santas, etc) and glasses. Generally you see those generic costumes and items in customization mode
