I've just started buying back the games that I missed in the last six months or so.
Fish tales, the first game I ever bought has made a return to my collection. LOTR was another game that I bought again recently, only to sell it on fairly quickly again as I still found that I couldn't get on with it. TZ has re-entered my collection again for a while. I sold my original one to make room, when I slimmed down from 14 to 8 machines a couple of years ago.
