Thanks to those who volunteered! Holy smokes, I didn't think the group would fill up that quickly.
The third group is getting an interface goody that I wasn't able to give to groups 1 and 2. They're also getting the original backgrounds, since my attempts to filter them further did not go as planned.
I think the third group is also mostly composed of players who haven't played the old game, or are fairly new to visual novels (?), so I'm very interested to see how this goes down. Thanks guys and gals!
