Hey so why is Morrowind not on Xbox Market Place. I mean Skyrim is pretty popular now, many people would want to try out Morrowind.
Cause Bethesda didn't think it was worth it? Because Microsoft doesn't want to do it? Because it's a relatively big game? Because Morrowind is a lot better on PC then on X-Box and can be played by all recent pc's anyway? Because Bethesda simply didn't think about doing it?
If none of those reasons sound good enough then think of some others, I'm sure there are a few.
