Star Citizen amazing fantastic! That was a joke never bought and it do not want to touch it. Full Release date? Perhaps maybe in your life time or your grandchildrens life time or never!
A more serious answer?
World of Warcraft
MMO. I played it in the Beta. I played it over 3.5 years when released and most popular time was when Wrath of Lichking expansion was released with awesome PvE Raids
and good PvP
! During this time Wrath of Lichking Expansion WOW MMO reached its record in popularity and despite only PC game (not supported consoles or mobile phones) it reached over 12 million active players.
WOW MMO is the only PC game I know for sure that I and my brother and my sister so all my siblings have played.
Eventually I got bored and quit it though and to much time sink for me.
