I've been thinking for a while about doing some more side projects and it got me thinking... what about an online BE game?
There would be several things to decide here, including what platform (flash? unity? something else?), what genre or style of game, what each world/level might be like, things you can do in the game, etc.
I think of the best games as being never-ending, so that would mean either sequels or expansion packs (haha yes!). I also like the idea of having backstory or quest text being something like a good BE story. Of course as many great BE animations as we can fit would be good, and tons of interactive BE would be awesome. What about different girls? Would you have people join your party, or would it be more like you can start over with a new girl you make in the character creator? If it was multiplayer what would the multiplayer interaction be like? Something straightforward like avatar chat, or maybe something more experimental like being randomly selected as "growers" and "growees".

Should all growth in the game be permanent or temporary? How much action versus adventure? How difficult should it be? Puzzles? Minigames? User-generated art? Focus more on tools and making a great editor?
Imagine, what would your perfect BE game be like? I'd like to hear your ideas and inspirations to help me guide my motivations.
