We shouldn't have to choose between the two. But for three of my closest friends so far (hencforth to be referred to as L., A., J1., and J2., respectively), getting married meant cutting off the relationships we've had for more years than they'd been married now: hanging out, okaying boardgames, and most importantly, playing role-playing games.
L. was one of the best players in my home game group: showed up every session, was enthused enough with whatever setting we're playing in at the moment as well as with his character, and took care of reminding players about the next game session. On top of that, he was also a very good friend who I hanged out a lot with. All of which promptly changed when he got married.
Mr game group which has stood intact for nearly 20 years fell apart, although L. was not fully to blame for that. Now, we're trying to rebuild the group and start a game of D&D 4E (as well as Savage Worlds, I hope). Most of the players are quite tied up with Real Life(tm) and things are further complicated by geographical separation. Still, we've got about four players that can be rounded up, L. included.
What strikes me as funny is the fact that these people claim not to have difficulty finding time out for gaming. Surely you don't have to be with your spouse 24/7! That's be hell. Would it kill people to have a little afternoon off each week for gaming?
I'm all for my friends' happiness(-es), but surely anyone can see that eschewing hobby time is very unhealthy. Things shouldn't suddenly change just because you're married. Dumbasses.
