(Rather than link to BGG, I've decided to link to my comments on the games) The multiples:
- Phoenicia -- 12
- Strat-o-Matic Baseball -- 8
- Caylus Magna Carta -- 6
- Roma -- 5
- Shadowfist -- 5
- Notre Dame -- 4
- Tichu -- 4
- Augsburg 1520 -- 2
- No Thanks! -- 2
- Smarty Party -- 2
- Stage II -- 2
And the onesies: Colosseum, Control Nut!, Diamant, Dune, Flaschenteufel, Leaping Lemmings, Mah-Jongg, Power Grid - Italy/France, Ra, Ticket to Ride: Märklin Edition, To Court the King, War of the Ring - Battles of the Third Age, Why Did the Chicken...?
A few games I hadn't commented on. The WotR expansion seemed reasonable enough. Colosseum struck me as "Too many notes." Not bad, but could be tighter.
Did you play the Strategic Expansion (adding Galadriel, siege engines, etc) to the base game or did you play one of the Operational games? I think that the strategic expansion adds the most interesting elements (although a few of them are under-powered -- the new Witch King).
