My wife and her friends almost exclusively play that. I tried running Dungeon World/Freebooters, but my friends didn't get into the swing of it since the whole "they do everything" aspect of the system caused things to crash and burn as a result of not having the DnD-esque interplay between them and their enemies. Seriously, the first "what are you going to do?" Became two minutes of crickets chirping followed by my wishing I could the dice after the enemies started attacking and they decided that "I shouldn't have to roll to see if I get hit by the bad guy's attacks." After that failed session I tried to play OSE with them but they didn't like thaco or the fact that they basically had a 1 round combat day due to low number of abilities and low HP.
