Re: Computer Aided
Because, as I think has been discussed before, who has the time/energy to code WoD in such a way that everything is automated (and then how to account for RAW vs. interpretation, etc.).
@faraday
Which is exactly the opposite of some corners of the MU*; they like to know how the stats interact and things like diminishing returns when your stats get above X, but... in general, that corner of MU*ing has never had a problem with computer-run stuff. But that's also never been based exclusively on an RPG system.
Re: PbTA games
I think the biggest problem with PbTA games in a MU* environment is 'moves', and that they're meant for Player vs. Environment narrative, and so making CvC work with Moves (which are 'things you do when the narrative ticks them') difficult to do.
Re: LARP on MU*
Probably highly dependent on the system. I think Sanguine Nobilis (and its successor, LAMUSH?) used some concepts from MET Masquerade but built an entirely original system around them. I know that LAMUSH's wikidot explains combat and such in a way that is not how MET Laws of the Stuff runs at all. NWoD LARP is literally just NWoD, roll a d10, convert total into succeses, for example. So you'd still have to find something that fits/gets into what you need.
