I've been in 3 groups;
1. The first was dungeon crawl with a little roll playing; fun, moved the plot along without a big deal about consistant characterization. Got along great with the DM and the other adults, the kids where a pain in the ass. The kids ALSO slowed things down a lot; got annoying after a few months
2. Community amatuer hour theater. Dropped it after 3 weeks.
3. 3rd edition D&D, which I hate. DM was obsessed with characterization and such. Group tended to be noisy and slow things down, so I kept quiet to minimize excess chatter. DM complained because my character "wasn't contributing to the group", whatever that means. Told him my direction for the character (really stong yeti who eventually turned into an incompetent magician, based on his stats). Got certain stats dictated for no reason, Got my alignment changed arbitrarily; DM also made too big of a point of making obnoxious NPC character. Wanted an eastern mythology based campaign, yet kept rolling up random monsters which didn't fit in that world, such as beholders, and random monsters could get the entire party killed quite easily. Oh, and clerics didn't exist so any death is permanent. Players were cool, but everything else sucked. DM took it WAY too seriously.
2/3 of the games I played in sucked. It's not necessarily hard to find a group, such as asking around in gaming stores, the problem is finding a GOOD group. Based on my experiences, I'm not sure I even want to try playing again. I want to have fun playing, not having to seriously obsess over getting perfect characterization and making a 10 page outline on my characters past, fear of snakes from child-hood, and what his favorite cheese is.
