Another game i play at times WOW, actually does a good job of reviewing forum suggestions, and implementing the good ones in patches. Obviously, with a game base that huge, there are numerous suggestions they disagree with and do not implement,
but the ones that they agree with, you see frequent patches tweaking the game.

WOW obviously has a bigger staff, and players pay a monthly fee, so their expectation to new content is a bit different.
Dom III players do not pay a monthly fee, so our expectations are rightly less, in terms of constant patches.

But the answer is, of course, you make the improvements, then sell an add on, so you can recoup some of your investment in time.
