Right. I am also a fan of collecting and painting miniatures, building terrain, etc.
My concern is that we don't "need" Dwarven Forge or great minis to run a physical game - though it sure is nice.

But on the VTT, maybe you will "HAVE" to get the black dragon digital mini to use the stats for a black dragon. My understanding is that in games like MtG Arena, you can't use cards that you don't own. I think this will be similar.
And I'm not sure if the digital tokens will actually be at a "fraction of the cost." I expect the digital miniatures to end up costing about the same as what an equivalent Reaper mini would cost - with the added complication that WotC can yank it from you at any time.
