I'll say same to you as I said to Veq.
Don't rush.
You have a game here people love. It has a good story, great characters and nice renders. Rushing something out would be an injustice to you and the game. It's one thing to have monthly content it's another to have content you are happy with.
Rushing would either make the updates smaller or reduce the quality both of which would be counterproductive. Sure you'd have an update out but would you be happy with putting out less quality than you have been?
The only thing people ask is a heads up. As long as there is no radio silence most folk are fine.
As for those that aren't fine with it, well they would complain if the quality was low so either way you'd have a whinging bint on your hands.
If you went 2 months without an update and remained quiet, then people would start getting annoyed but generally, especially with good quality games, people are quite understanding.
