I have a lot of good stuff to say about this place so far!
Despite the tendency of similar WoD MUs to frequently have staffers that are aloof, if not downright mean, my experience so far is that every staffer on SanFran is super friendly, super diligent, super helpful, and enthusiastic about creating a fun space to tell stories.
I was wary at first of the decision to allow Mage and Sin-Eater alongside templates like Vampire and Changeling, as I've seen the power disparity elsewhere make cross-sphere PRPs all but impossible. But so far, Xapham has made a lot of solid, common sense adjustments to various Sin-Eater abilities to 'un-break' them. Likewise, Azrael has made a number of adjustments to Vampire in order to make it a more robust, tough template, when the RAW end up delivering a creature that is inordinately squishy compared to most any other gameline. I'm really seeing the staff here turn the dials to deliver a level playing field, as best they are able, with a focus on amending template Advantages that already exist instead of tacking on a bunch of new rules in addition to what is there to begin with.
I do think Changeling and Werewolf will need for a couple of serious bones to be thrown their way to be brought up to speed with the adjusted vampires/sin-eaters, and I'm curious as to whether anything will (if it even reasonably CAN) be done to rein Mages in. That said, I have a lot of faith in these staffers right now.
The player base so far has been nothing but friendly and welcoming. That's not to say there's no chance of the usual MU melodrama eventually cropping up, but there's a good foundation here, right now.
If folks are looking for a good time playing 1E, mixed template, and if they've been turned off by similar projects for whatever reason, I think San Fran is 100% worth checking out right now.
