I see what you mean. I am not actually dividing between mediums, as much as means.
When I search using "
CRPG" I find the sorts of computer games that I intended to indicate, which are not open forum RPGs, MUDs, etc. So I think it is reasonable to use that label to mean games that don't rely on [imagine] in the ways discussed in the OP and investigated in my earlier posts such as #205 and #220.
Equally, when I search using "
TTRPG" I find the games I intended to indicate. Conceding your point however that I did not really intend to exclude imaginative-RPG (IRPG) based on medium.
@FrogReaver I see that my flippancy obfuscated my point. The "
TT" I referred to, and the "
C", were intended to evoke the labels above, and the games that would be categorised under them, not
medium per se. I anticipated that the reader would add "
RPG" and see what was intended... but that was plainly less clear to others than I pictured.
