With my usual metric of game enjoyment - hours of interesting playtime divided by price in $ - Star Citizen actually does rather well, for a $45 entry it's definitely generated way more hours of actual fun with friends than most $60+ games we've bought.
It's definitely also generated lots of frustrating hours, but that's rang true for said $60+ games as well. I really wish there were more other games which do some of what it attempts.

ED was fun, but me and every one of my friends who're into space stuff have all individually burnt out on that game due to the frankly insulting level of grind.
NMS turns out to simply not be the gameplay we're after, so I have even less playtime in that than ED.
So far, Space Engineers and Avorion have been doing the best in that regard, still hosting a 24/7 Avorion galaxy for us in fact.

X4 has been collecting plenty of hours of playtime for me as well, but it's lack of any kind of meaningful multiplayer with friends does lessen the enjoyment somewhat.
