Brad et al,
OK, yet again, I'm way late to the discussion.
FWIW - My general view (as a software architect/developer for the last 15 years) is that you give the developers most of the time they want. In my world, it always seems to be a game (no pun intended) of diminishing returns. I'd use all the time (and more) to make something better if allowed. The question usually is, what are the users/gamers getting for the added effort?
If you feel forum/beta feedback will dramatically improve the game-play experience then go for it...this is something that I usually don't have the luxury of with ordering, inventory, and provision system design/development.
As somebody that has already pre-ordered the game, I don't have a big problem with a longer development cycle(s) especially if I see/hear that modding and python support become more robust during the cycles.
All just my opinion of course. Keep up the great work!
