A successful buisness model, meets the goals it sets out to achieve, it doesn't continually change goals, but I hear talk about EB2, EB 0.9, and how great EB 0.8 is, when EB 0.8 isn't even out yet, or close to being polished...
I'd just like to say that I think this is the flaw in your logic that's forcing you to trip up over EB apparently so often.
It's a mod. And like most mods it's made by fans of the source material who wish to mold it into something greater. You can't compare it to any kind of business project. It's a hobby, if anything. So at the end of the day they can expand on their mod plans, and it shouldn't warrant rants (unless the modders have broken the game, then we can burn them!).
