Think of the genres that you can have in novels (well, apart from chick lit) and you can pretty well find a role plating game to deal with it.
This is obviously the greatest flaw in modern RPGs. We've all been Fangar the level 13 wizard, heir to seat Garnak. However secretely we all want to role play as Cassandra, a down on her luck marketing excutive who takes a much needed vacation with unexpected romantic consequences.
May I ask, what do people who are interested in pen and paper RPGs think of computer RPGs? I've played the latter a lot, loved Deus Ex, Elder Scrolls (especially the newest one), e.t.c. However I've never played the former.
