Interesting concept. Normally I already have problems with games because of the sound, most of the time I use headphones, this would be a game that I'd very rarely be able to play (at least using the voice mode, and without voice mode this game is pointless imo.)
Also, it may just be me but I'm really getting tired of "beautiful hand-drawn environments". To be honest if I wasn't told that these games are hand-drawn I wouldn't know. Which begs the question, does it even matter how it's drawn? The only way I could see it matter to some people is if they have something against computer technology, but then these are computer games so that doesn't really work out.
