I heard about virtual gaming tables as quite expensive devices.
What table do you use for this project? What product? How big is the screen size?
Do you use the original miniatures on your table or are they virtual, too?
Or do you simply speak of playing online via a platform like vassal?

Btw: I do not play the game Mortheim. I said we play >in< Mortheim - just the setting.
We use the miniatures but RPG rules (the german Trauma Universalrollenspiel from FlyingGames.de) unfolding
even more complex stories and gaming as in the tabletop.
Such a map of yours would be quite handy for me being the game master.
Printed maps are much more convenient for RPG scenes instead of building up 3D scenery like in the tabletop game.
