Doubt crossplay will happen, as is there not already a ps4 version which isn't crossplay with pc?
also update, i have zephyr made and valkyr building, remembered to attach my amazon prime to twitch and got trinity prime, and i've leveled up and formaed and re-leveled mag prime.
where i am in the story: most of phobos done, ceres junction open, and almost all of leading up to those points done (just handful of mission nodes here and there not done, plus havent looked into cetus). 3 left syndicates are also past the first rank increase.
got a few friends playing, all on at different times. one has 1800 hours then stopped playing for almost 2 years, another started when i did, and the last one is a couple mastery behind.
