I'm in four now (yeek), but what I've found is that so long as I make sure that there are differentiation, I'm fine. Like, Charming, I play in two places but at City, he's more David Nolan than his Charming version and it lets my brain wander, but I was playing Danny in two places and it effectively killed the voice at both because he was the same and I had no canon support in either, which sucked.

I will say that it helps that two of the games have no reqs because it allows me to focus on City when and not feel guilty.

(Also, if we got a Proteus or a Van Helsing, that would help along my Victor decision immensely)
