Hmm. If he has, I doubt he played it past the first stage or two. He was friends with Linka for a while, and she stayed in his dorm room for... some reason. Possibly Darkness. So it's feasible that he's at least been exposed to the game, but very unlikely that he's sought it out.

Am I right to assume questions about dropped characters are alright?

What has Saiga been up to anyway, since breaking up the cult and everything? Did she find a good job?
