That reason being twofold:It's group dependent and I find that the larger the group the worse it is. Playing online also seems to make it worse for some reason.
a) it quickly becomes obvious when playing online how much work the DM has to put in preparing maps and encounters etc. and so there's a certain degree of soft-edged pressure to go along with it
b) corollary to this, it also quickly becomes obvious that if-when the players do go somewhere unprepped the online systems don't lend themselves well to drawing quickie maps on the fly such as one can do on a chalkboard or whiteboard
(side question: do any of the online RPG platforms yet support using a digital art tablet in real time to draw maps, such that what the DM draws on the tablet immediately appears on the players' screen? Relevant in that it's light-years easier to draw with a pen than with a mouse).
