I run games at a Meetup and ran into a situation that I could use some guidance on.

I had an autistic player show up who derailed the game. I was told by the Meetup founder that the individual was autistic and if I was willing to let him play in my game, to which I said yes as I never like turning people away. Plus, I've had high functioning autistic players before, and it was never an issue.

The individual immediately started derailing the game by wanting to make a character from scratch at a one shot with pre-gen characters. He also kept interupting the game by talking about characters they played in other games. There were other distractions as well, including strange snacking habits.

Everyone at the table treated him with respect and propped him up but after the game they said that he was too much of an issue.

At one point in the game, he mentioned how he has trouble making friends and has been kicked out of other groups, which makes my heart sink.

Due to his distractions, we only made it halfway through the one shot, so I told the other players that I would allow him to finish the adventure as he was grandfathered in. After that, I'm going to have to decline him.

Im just looking for any advice, including if there's anyway of getting through to him about the issues he causes. I just met the guy, and feel awkward pointing out his issues but I also feel for him. Any pearls of wisdom from you all?

Obviously forgotten realms and dragonlance books. From wargaming side we have warhammer and battletech. But what other rpgs have good fiction accompanying them ?
