BGO Extended 2.0 expansion (fan expansion for Through the Ages)

Fan made expansion used on Boardgaming online (called Extended 2.0 variant there).

It consists of 8 new leaders (2 for each age), 8 new wonders (2 for each age) and some other minor changes (see below). At the beginning of the game new leaders and wonders (for each age) are mixed with that of the base game and a set of 4 (per age) is selected at random (so number of cards that will be used in game does not change). This way each game offers slightly different cards set. There is an option to make selected cards visible (so players know which leaders and wonders will be in the game) or hidden (so until they are drawn from civil deck they are not known).
