Yes, the way we play is mostly dependent on the player. I say mostly, because I will take a look at which characters I think would play well together, and try to drop them in the same area if it makes sense. I highly encourage you to play with your fellow villains, but if you really don't want to, I have no issues running a solo thread for as long as that makes sense.
For as long as it makes sense, because there are going to be moments when your characters will cross paths with one another. At that point, I'll drop you both into the same thread for ease of play; but there is no requirement for you to RP with one another if you don't want to. Again, highly encouraged, but not enforced.
