Great People slots: As of normal buildings... Temples --> 1 relic; amphitheatres --> 1 book; art museum --> 3 pieces of art; archaeological museum --> 3 artifacts; broadcast center --> 1 music piece Wonders: Palace --> 1 wildcard slot; TGL --> 2 books; Bolshoi --> 1 book, 1 music piece, Mt Michel --> 2 relics; Hermitage --> 3 pieces of art; Oxford --> 2 books; Broadway --> 1 book, 1 music piece; Sydney Opera --> 2 music pieces And there is a GM that can create a bank with 2 wildcard slots. I don't think the # of TRs matter, either. However, according to the posts earlier on the necessary accumulated tourism: if this is correct, then it's actually vital to meet everybody as early as possible (which may or may not be feasible without Cartography). EDIT: different religions and Enlightenment only affect religious GWs (relics and religious art?) The Christo Redentor counters the Enlightenment malus.
