I here what you are saying but I am also pretty far into creating the system. I am for the most part avoiding feature cheap. The part of my game that I really love is a secret objective system. I may just be to close to it, but I just don't know any games that I could hack that system into well enough. So I decided to build the game system that would support that idea.
There are a few features that I like but are on the back burner for if I have time.
