Does system matter?
Is there one roleplaying system that you prefer to play above all others? Are there systems that you absolutely won't play? Do social considerations override those preferences? Would you rather play with the right people, or the right system? Or are the right people the ones playing the right system?
Would you rather play something familiar, or try something new? Are you still playing the first system you started gaming with? When you try a new system, would you rather that it be similar to one you know, or something crazy and different? Or are there certain features that you know and love, and others you don't mind if the system experiments with?
Would you rather play the perfect system, or one that's not quite perfect but you know inside and out? Are there systems that you originally hated, but fell in love with when you mastered them? What about the other way around? Any system that you used to love, but now don't remember well enough to use properly?
