What term describes public works or games financed by wealthy individuals?

The correct term that describes public works or games financed by wealthy individuals is "Munera." In ancient Rome, "munera" referred specifically to public services and charitable acts that were often funded by affluent citizens as a way to showcase their wealth and generosity to the populace. This could include providing gladiatorial games or constructing public buildings, which were not only acts of philanthropy but also a means to gain favor and status within the community.

The other terms refer to different concepts. "Ludi" pertains to games or festivals, particularly those held in honor of the gods, which might have included the munera but is not specific to funding by wealthy individuals. "Agenda" relates generally to things to be done or a list of items, lacking the specificity tied to public works. "Collegia" indicates associations or guilds of craftsmen and other groups, which does not relate to the funding of public spectacles or facilities.
