Richest is an interesting word because it's so subjective. It does not necessarily mean most detailed\complete(which would probably go to one of the Warhammer franchises) it does not even necessarily mean most expansive lore(Which would probably again go to a Warhammer franchise or perhaps D&D)
I would have to say that for me the 'richest' would be from Fallout. There's a lot of lore to it, and it's very interesting and unique. I feel that with a few more games(not likely) Arcanum could be number one for me in that regard. It just feels like it had so much room to expand upon. Would have been highly interesting to see the Arcanum 2 that troika never completed. Was originally supposed to have a Journey to the Center of the Earth type theme.

Dragon Age. A few hours into DA:O I became convinced that there must have been several previous games, because I just couldn't comprehend that much lore being dreamt up for one game.
Most of it is just European History with fantasy tropes injected into it and a dash of Tolkien. So it's not so much 'dreamt up' as copy pasted and then someone went through it with a thesaurus of fantasy words.
Orlais is France, Ferelden is England, Antiva is Spain\Italy, Rivain is Morocco, the Free Marches are the German states. Anderfels is the Western Roman Empire(Holy Roman), and the Tevinter Imperium is the Eastern Roman Empire(Byzantine.) They barely even change the allegory of the Catholic Church and Jesus' death. The Elves function as gypsies and Jews. The story of the destruction of the Elven homeland is essentially the diaspora of the Jews when the Romans(Tevinters) expelled them from Israel. The Qunari are the Ottoman empire and the original expansive Muslim Caliphates.
Even most of the buzz words they use are taken directly from history: Apostate simply means someone who has left behind a religion, and was a term used to brand people as heretics from the Catholic Church. Maleficar is just a very slight derivation of the Latin word for 'witch.' And a Chantry chapel is literally already something that exists, where a priest or group of priests would sing songs for a worthy cause such as for the soul of a church donor.
The allegory of the Golden City is basically the Tower of Babel with Mages and pseudo-orcs. They took the inquisition and the Knights Templar almost without change. The spirits and demons are angels and devils. And blood magic is hardly a new concept, the Jews smeared blood above their doors to ward off the Angel of Death in Egypt. The Mayans routinely performed blood letting(usually by cutting either the ear lobes or the penis/vagina with a knife. They very rarely actually did human sacrifices) in order to renew the world tree with their blood and to keep the 3 tiers of the world from collapsing in on themselves(which is actually what is supposed to happen in 2012.)
Which isn't to say it's bad. Most fantasy lore is assembled from mythology and history. I would just personally give more credit to game lores that combine things in unique ways and do a better job of disguising their sources.
