I'm a PC player so I probably won't get to play the second one for quite a long time, but I'm excited as well. Kojima doesn't usually iterate in a straightforward manner in sequels, so it's hard to know just quite what we'll get out of it.
Death Stranding was already one of the most novel and interesting games I've ever played in both story and gameplay, so I'm glad we'll get to see some more of it.
