Noooooo. No detritus. Markers must blend. Dice may be rolled on the table but not kept there. Always about the pretty.
I agree, but it boils down to “What are you modeling? – the pieces/parts or the action?”
The answer -all individual taste- indicates the sliding scale applied to not only markers and such, but to the figures/terrain as well.
Again: What is it that you are modeling?
The answer (imo) is “Lots and lots”, but it is the prioritizing of all those things that leads to the variety of tabletops seen.
