actually I missed the happiness things, that is right - I could add that back. I looked for suitable venues, but somehow missed more - when actually finishing it up I wasn't really sure the stadiums were fitting though. I can add them, however since major replaces minor that actually results in less effect than having theater and opera - generally I would certainly increase the cost if there are more buildings.
I can not find concert halls or auditoriums. More fitting would probably be convention center, fair ground and indeed the sports arenas (basketball court and the two stadiums) and recreation center I guess - I could add them all - but that would make this event extremely powerful (adding another up to 8 happy and culture/turn for each city is huge) and I'd rather not have events that are completely out of whack. As is a cost of 2000 gold to add 4 culture per turn per city in the late game is already a mighty good investment - add to that 4 happy per city and its great, adding any more buildings would be way to much for the low cost.
