After a couple of comments from Mike and Bobby, I thought I'd do a couple lists like Bobby did. The games will be listed in no particular order and all based on the games I own that are not yet played...
Five games I really want to try
Gulf, Mobile & Ohio
Five games I won't likely ever play, but won't get rid of
Honor of the Samurai
Cosmic Encounter (which is not to say I won't end up playing this, just not likely to be this one - maybe when the new FFG edition shows up)
Axis and Allies:D-Day
Axis and Allies:Europe
These are just part of my collection at this point. MAYBE I'll play and A&A game with my son someday - maybe.
Five I'm probably just stuck with...
War! Age of Imperialism
Pirates of the Spanish Main
Age of Mythology
