This reminds my of the verse from "The Roguelet's ABC" about the original, text mode, rogue:

U: There's a U -- a Unicorn!

Run right up and rub its horn.

Look at all those points you're losing!

UMBER HULKS are so confusing.

I think favouring clear and unambiguous design over one that is, perhaps, more aestetically pleasing but less clear, is quite important. You don't want to make a mistake and end up losing a run just because you thought you were looking at one thing and it turned out to be another.
