I know this now really archeo, but while I'm finishing my researches on Dragon's Eye I just want to to suggest you to have a look at an interesting release which might see the light by the end of year. It looks like is going to be a top view CRPG Ultima style for C64 and as far as I could see from the preview it looks very promising.
Here you can download the playable preview.
Edit: Screenshots have been updated from the previous post. Now you can actually see how the project is progressing even from a design point view.
