By "character", you mean the Champion?
Among others, yeah. I think some NPCs mention it, but it's an important detail that everyone really ought to address. Actors like Keith David, Peter Cullen, or Fran Drescher are much more distinctive for their voices than for their looks.
Why oh why, man? That's like the one thing we're free to imagine on our own. So much else is described to a "t" - y'know, being a text game and all - I enjoy being able to hear the voices as I prefer.
The reason to describe the champion's voice is the same as the reason to describe the champion's physical appearance. Yes you could use your imagination, or you could use your imagination with the assistance of some descriptive text.
Also, it'd be a shit-ton of additional writing and coding. Like, a MASSIVE load of writing and coding.
I'll buy that, sure. IMO it's not that difficult to write text - I'm considering offering to do it myself, though this community hasn't been super-welcoming toward my contributions thus far - but coding is an entirely different story. I know very little about it; I would think that if the program generates a page already, it wouldn't bee too difficult to add an extra line or two of text to that page, but I could easily be wrong in that assumption.
And then people would claim that their Champ's "unique voice" (barf!) should be added as an option.
Well people will ALWAYS complain that the silver platter you served the world to them on isn't quite as shiny as they'd like. I get why some people would find this attitude tiresome, but I'm content to entertain such complaints, as long as they don't turn into abusive-level demands. Everybody has the right to say "I wish this was better", as long as they don't try to bully you into doing the impossible NOW NOW DAMMIT NOW.
And I haven't even touched on accents yet. Oy vey!
Ach, sacre-bleu! Faith and begorra, otaku-chan! Dos vedanya, mein freund!
