How do you define abandoned? I've started lots of projects that I haven't finished, but I don't consider them abandoned because I only got far enough to judge the viability, playability, test concepts, or whatever. Others I've done designs for, and never even started for one reason or another, but again they're not abandoned, I just chose not to make them because they were tehnically limited, not fun, or whatever. Once I've got past that point, I've not given one up yet.
So that gives me..
10 Completed (100%)
0 Abandoned (0%)
