I understand your issue and have a similar situation. Now that I have other responsibilities in life (young child, house, wife work etc) my gaming time is massively reduced and I'm finding myself being much pickier about what I play. Gone are the days when I would happily grind away at some game just for the sake of playing, now I reaaly have to feel like I'm achieving something when I play. Consequently many games that 10 years ago I would have loved just don't hold me any longer. Ah well, just the joys of getting older I suppose
