To begin with:
Hello from Australia. In brief I am, of all things, a veterinarian, as well as a musician and a writer who enjoys anything (of quality) that features animals or anthros.
I just had the chance to play the original game (or re-release on CD, so not quite the original), and thoroughly enjoyed it. I like such games in the vein of Monkey Island, so it was nice to play a purely furry game.
I'm looking forward to the next installment of Inherit the Earth, irrespective of the style or rendering format it will be in (2D or 3D, or both), and personally I think releasing the game in episodes is a good idea. Don't be in too much of a hurry to rush something out; for what I understand you are a relatively independent game company, so I can appreciate that money isn't something you are up to your armpits in. I think we all can patiently await each episode, knowing that giving you the time to iron out the bugs will make for a much more enjoyable gaming experience
As someone else already mentioned, I would be willing to make (monetary) donations if they would help.
As for the orientation of the game... well, personally, I found the original game to be lacking a little (not that I blame the developers, as I know how the original game was "re-realised" for a younger audience), and thus I hope that this game will have a more mature slant to it. By mature, I do *not* mean sexual, at all.
Anyway, irrespective of how the final product will be, I am looking forward to it. There aren't nearly enough quality anthro games around, which is a pity.
