From my viewpoint - The basic difference between a tabletop RPG and a computer RPG is that the tabletop RPG involves roleplaying, and the computer RPG... Doesn't, particularly.
However, that means that pretty much any mechanical trope that can apply to one can apply to the other, common to do so otherwise. RP Gs
is a cross media genre that can be divided into Eastern, Western, Roguelike and Tabletop, while Tabletop games can be divided into (at least) Miniature Wargames and Tabletop RP Gs
As for the title - This should be an article, there should be an index of tropes, it might be useful to divide the index into 'videogame tropes', 'tabletop tropes', and 'both' but not to make those separate pages.
