I am a PnP player and i absoluteley dont.
The ammount of work to go into graphical representation of each session would be tremendous, meanwhile it limits my ability to worldbuild and to plan encounters.
Meanwhile i also love OS2. Also 3 out of 5 of my players do too. If were already talking anecdotal evidence.
I get that you don't like the idea, but.. not sure what you mean by the amount of work. Anybody today that uses say, fantasy grounds, or table top simulator, or role20, which is significantly more work that GM mode would be (assuming how DOS2 was) actually makes it easier to world build. And you don't have to make a "video game" in as much as interactive battle maps. It would be easier for players and gm alike actually.
I'm not trying to convince you to like the idea, I get it and don't really care, but I'm only addressing the idea that it would be such a tremendous task. It would actually be easier than the other systems now widely used.
