I'm gonna copy/paste for a sec here, because this has come up before... in the end, it's up to NCrow, of course, but previous discussions brought up various points that must be considered:
------------VVVVVVVVVVVVVVVVVVVV-------------
<I'm not sure how likely that is-- for two reasons: voice acting is expensive (it's different with plap noises or wet noises because anyone can make them) and the second reason is file bloat-- sounds are big files-- with such a diverse cast, it would blow up the size of the game very quickly, and GW is already not so small. It's all fun and games until you're DLing 7-8 gigs on the downloader, at the mercy of the server connection speed. I get what you mean, I'm just not sure the logistics are as feasible as we'd like them to be. NCrow is good, but we don't want to break them...>
These points were brought up in the Discord under much the same circumstances. NCrow may try it anyway, but between cost and bloat <shrug> I wouldn't blame them for avoiding the headache, especially with a cast that big... and re using voices seems a bit cheesy-- I don't think NCrow would dishonor the ladies like that... even the mean ones.
