[arch-dev-public] cleaning up games in extra

Hi! When I was adding licenses last week I went through the games category. I know we don't have a lot of games in our repo (relatively), but some just seem to be there for historic purposes. I'll start making a list of most ancient games for you to comment on which we can delete. That is, if nobody says something like 'please don't remove them, I like playing old games' :) Ronald
