I was thinking over the last 10-11 months of Civ 4 and its aspects that I've never made use of in a real game. I decided I'd compile a quick list of all the things I could think of off the top of my head that I've never done in Civ 4. If anybody's actually done something on this list (and would do it again
), I'd be interested to hear about the circumstances. Also, if anyone wants to add their own additional things they believe rarely, if ever, fit into a game, please feel free. I will note that, in warlords, this list has already grown shorter (I've actually built a castle in warlords, though I don't know if I'd do it again...)

- Built a Castle
- Built Chichen Itza
- Built a Cathedral in a non-cultural game
- Built the Muslim shrine
- Built a Bomb Shelter
- Built a Hydro Plant
- Built SDI
- Benefitted from Environmentalism's bonus happiness from Jungle
- Benefitted from Theocracy's lack of religious spread
- Run Serfdom
- Built more than 3 Ironclads in a single game
- Actually used a Machine Gun in combat
- Taken an Amphibious promotion
- Given more than one unit in a single game the Commando promotion
- Built a Fort
- Built a Workshop prior to Guilds (or more than about half a dozen without State Property)
- Built an Offshore Platform (because you needed oil)
- Scrubbed Fallout
