Like most people here, I cannot wait for this to come out!
I've never played any fan games that weren't hacks/mods so it'll be interesting just for that bit. I'm especially amped for all the regions, been waiting for a game like that for a WHILE! :D A lot of people promise that in their rom hack but then never finish them because its such a massive undertaking for a hack/mod.
The graphics (bgs, etc) are a little inconsistant with each other, but they look great enough that it doesn't bother me personally. ;P I'm sure other people already mentioned all of this before though hahaha.
