I'm never buying season passes for DOA6 again...
See this is why people should not buy season passes at all until the information is completely revealed.
An example. Spider-man for the PS4 had a season pass that revealed everything on what you'd get from the pack from the developers themselves. DOA however (just like EA games with certain games), provides a season pass that may hint on what you'll get from the first set but leaves a "?????" from the rest of the package as if it's a secret surprise that'll be good. There could be a chance it might be worth your money, but that's a risk I will
never take, especially not from KT or insert any other company that chooses to not reveal it's information on what you'll get in the future. I will wait till all that shit is revealed until the end. Same with Nioh, never bought the season pass (if they even made one) so I waited till I see a trailer on what the actual content they are giving me is all about before I toss my money at them. Obviously there's a chance that the content will be superbly good (It's Nioh durrr), but it's still a risk I wouldn't take because you never know, publishers and developers mess up sometimes you know?
I think what people should do is wait till every single package of that season pass is released and then buy the season pass right after it if you'll like what it came with (or buying things separately within). I will never ever straight up buy season passes day 1 unless I know for sure on knowing what's inside the package. But of course, how you spend your money is entirely up to you. It's your money.
