This is a list of all the games that I have completed - at least, the ones that I can remember. This is only here as a record of exactly how much time I've wasted when I could have been doing other more useful things!
NB: It's likely that I might not keep this list up-to-date - more likely, I'll use my Neoseeker completed games list to keep track of things.
