It's something I can play around with at work on my laptop and on my PS4 at home; it's pretty much the only AAA MMO out that has crossplay between PS4 and PC.

It's also a good gap-filler/fallback game when there isn't anything else I'm interested in playing, since you never really run out of stuff to do.

And the story is good; it's world, lore and characters are engaging; visuals are top notch for an older MMO; etc.
