Not really, I don't consider jotting down couple of sentences on the forum an "effort", it isn't taking up much time either. Then again I like CM games, so spending a little time caring is the least I can do. I even started a thread on the Bay12 forum in 2011 to promote CM games, took me couple of minutes, but it has been read 1796 times, so why not?
CMx1 games still gets medial coverage, just three months ago there was a very entertaining communal let's play of CMBO on the Rock Paper Shotgun site, another one was a year ago. I can see how people may be still buying CMx1 titles, there is nothing like it on the market.
I concur, probably nobody would. That is why there may be other ways to use it.
My bad, I used the figure LongLeftFlank used, without checking.
Well, if CMSF 1 is planed to return to the store, then it shouldn't go free of course. I'm saying there may be a way to use it better, giving out something for free is a very powerful marketing tool, even if its never happens, it may be worth considering or at least bringing it up.
