Tabletop Simulator is a single game that people will scan in the manuals and play pieces and build the logic so popular board games can be played multiplayer via the Internet on a computer. Graphics are not as good as if the manufacturer made a native game but the play style should be the same.
I never tried it but really want to give roll20 a go to try D&D again.
Oh man I haven't played D&D since college.
I can give tabletop simulator a try, but my sons are surprisingly computer illiterate for their generation. I can hope.
