Excellent point there crashcamp, all my games are A's but when they're paying up they can go all the way to Z's
Someone mentioned that some games are fun for awhile then show their true colours, I think that is why you need several games in a collection. I don't think pinney buying is an addiction but a necessity to keep your interest up. All games can get boring if you flog them every day for hours. I believe I my have hit the right number and mix now as I don't feel the urge to buy more as I did not so long ago.
