This seems like a case of an indie/niche game expecting a bit too much from itself.
One of the things about making indie games is that you have to realistically look at your market and costs. Expecting to sell a gajillion copes just because you think you've made the best game since sliced bread should be tempered by some heavy reality checking.
I honestly don't like to see PC games fail, even if they are not my cup of tea...but developers need to know their limits as well.
If you make a game where your intended target audience has to really 'get it' to enjoy it, then please see the results of that from RTW and APB.
