You expect me to remember details of a conversation that happened 7 years ago? I can barely remember what I had for breakfast.
Or was it 3.5? It would have been the same gaming group. In any case, I remember talking about centaurs and climbing cliffs/ladders with the group and the questions about how things would be physically responsible.
But even if I just dreamt it (which would be why Little Jeff had a unicorn head*) this thread should be evidence that verisimilitude/believability would be an issue for some people.
I mean, unless you're just calling me a liar.
*I kid of course. But we did have Big Jeff, Middle Jeff and Little Jeff as part of our gaming group for public gaming. Mind you "Little Jeff" was probably closing in on 6', we just had an overabundance of Jeffs and the others were well over 6'.
