Who's your favorite Great Person and what do you like to do with them? In Civ5, I find the Great People slightly underpowered. While their main ability is fine (Discover science, culture bomb, trade mission, etc), all the structures they build are pretty worthless in the grand scheme of things. In my mind, the better idea would've been: Great General-Bring back the 'Lead Generals as a Warlord'. All that experience and unique upgrades it gave helped upgrade your army. Plus it was neat having a unit led by a great leader. Great Scientist-I'd retain the build academy feature but I would double or triple the benefits from it. Great Engineer-"City Expansion"-Instantly build four structures (starting with least expensive) in a city. Great Artist-Discover a free social policy. Great Merchant-One of two things can be added- A. Land on a resource within your borders and when the unit is consumed, the resource output from that tile is doubled. B. Land on a resource outside of your borders and when unit is consumed a colony is established.
