Well yeah... that was sort of the point. Reductio ad absurdum.
The proposition that was made was that arguing against the removal of this or that aspect of the game because its removal harms the ability to roleplay is invalid, since one can simply imagine whatever is necessary to compensate for the removal. In point of fact, one can simply imagine ALL of it, so the fact that one can imagine this or that aspect of it is moot. Every single thing that the game provides is something that can be imagined. If the fact that one can imagine it is sufficient to compensate for its removal, then the game might as well not exist at all, since all of it can be imagined and thus the removal of all of it can be excused by the OP's logic.
The reality is that the game's explicit purpose is to provide a framework within which to roleplay - to represent aspects of the character and the world and provide feedback to aid in imagination. The only valid issue is whether or not this or that particular feature should be included, and that issue has to be settled in some way other than "It's okay if it's removed since we can imagine it," since, again, we can imagine ALL of it.
I'm with you.
It's essentially what I was getting at earlier, when I posted:
"After a fashion, you are of course correct, HOWEVER, part of the power of video game RPGs is to give visual representation to the roleplay you are imagining. When certain features are ommitted, you end up right back to where you were when you were superimposing The Forest of Mirkwood over the living room floor. . . having to visualize things that just aren't there to be seen.
The really advanced RPG games like Elder Scrolls is that so much of the visual representation is well taken care of, that the main thing you have to entirely imagine and roleplay the type of person you are, and your backstory prior to entering the game. The game offers you visual support for roleplaying much of the rest.
Not being able to jump very high, or not being able to merge certain spells, or not being able to wear just a cuirass and no pants, or just greaves and no upperbody apparel, detracts from that visual aspect.
Its like. . . if you are roleplaying old school with toys, yes you CAN pretend that a My Little Pony is Conan the Barbarian. . . . but that pretend is much more convincingly backed up with a He-Man action figure, who at least looks the part. Likewise, if you want a Pegasus representation, then the My Little Pony is much better suited to the role then Cobra Commander from G.I. Joe. lol "
