I actually installed and completed my old original version of the 1991 classic Another World a couple of months ago, but now I've just discovered that it was re-released last year in a high-resolution version so I'll probably have to download and try that one as well soon..
Another World download and more info here:

It's a free demo version there, but the complete re-release costs 7Euro
