...I feel like I've got the most unpopular opinions here, but I'll go ahead and post them anyway.
I'm rather glad that changing R. Parkers to Re-Tail, because every time I see that, I can't help but to think of the artist (Ray Parker, Jr.) of the Ghostbusters theme song. Maybe that's just me thogh, hahaha.
Shizue being renamed to Isabelle/Isabella is rather nice, actually. I love that name. It's got that assistant-type vibe to it, and I think it just plain suits her well. I can kind of see why they wanted to stay away from Shizue in America, though, since she's a Shi Tzu, put the first letter of the second word and the end of the first and what do you get?
(Yeah, I know it seems a little immature to think that way, but we gotta remember. Most of us are not in the main Animal Crossing demographic. I know I'm not at almost 22, but hey. I still love the series.)
I've heard Lisa's name is being changed to Reece. I personally don't care, both names are nice. Reece is a bit out there, but it's nothing too horrible. In fact, I find it pretty unique.
And Kaizo's name to Cyrus? I like that. It's a b.a. name for a b.a. type character.
