Jim, I've also reached that point and the collection is at its apogee; this spring I'll be auctioning off all my EUROPA series games.  I've played all the GDW versions but not the GR/D ones and now understand that I'll never get to them.  I will need to do far more than just this, however.  But it begins now.  Have cut my wargaming magazine subscriptions to just a handful and am not ordering new games like I had.  Still have plenty on the bucket list that need playing, however!  Yes, I don't play ANYTHING well these days!
