BB2 because bb1 WILL be playable on pc eventually whether they want it to or not. And we may as well get the timer ticking on bb2 being on pc as well lol
Bloodborne: Complete Edition for PC, with new and rearranged weapons (I hate how the only strength+bloodtinge weapon is near the end of the DLC area), armor sets, and restored cut content. I'd especially love for them to go thru the chalice dungeons and eliminate most of the reskinned and duplicate fights.
Bloodborne is good enough to stand alone; I'm not sure where they could go with a sequel.
