Yes, they are and you fight some monsters which origin lies in ancient Greek, Egypt and China. But that's all. Religion is not mentioned in this game.

Well, yeah it is. :P A lot of those "monsters" were intricate parts of those ancient religions and there was nothing fake about the Oracle at Delphi. I mean, I'm not saying that broad actually was all seeing, but there is solid evidence she was real and played a big part in everyday life.

Well, it seems that I wasn't able to express my thought clear enough. There are some characters from Ancient Egypt. Like the Oracle, Zeus, Hades, others gods, several creatures, chinese shrines, egyptian tombs, and priests, but the main character just needs them for completing his main quest or side quests. They are just background characters, npcs.
The question is about rpgs which contain religion that includes games that let you play as a religious characters, like a priest or that let you get advantages from this character as a companion or a healer.

You made it clear, I was just making conversation. :P Sorry if I came off like was correcting or challenging you. I tossed in that ':P' to make sure no one thought I was being overly serious.

I was going to suggest this after playing it. I don't know how accurate they are with their saints, etc, but Legends of Eisenwald is definitely set with Christian influence, similar to Darklands (Blessings and the like are the only "magic" in this low fantasy setting). But as far as I can tell, religion isn't really mentioned (besides going to churches and using priests to buff party members) specifically.

I do like the mix though but sadly the mention of Hades and the Oracle in that game are the closest a lot of kids are likely to get to any kind of an education on ancient myth and religion.

Interesting question; while I can't think of any that haven't been already mentioned (such as 'Darklands', an excellent old game you can get on GOG), I tend to think that the Ultima series (those I've played from VII on) seemed to have some very moral undertones, yet not tied to any specific religion.

Wikipedia actually lists two games [edit: in that genre] (only one of which has a link) which follow are influenced by Christianity.

Of course, the alternative are many sandbox games out there (or simulators) in which you get to choose your own behaviors you follow religiously.

In this case Titan Quest is very educational. Kids learn that there are guys with strange names in a country of unknown 'Greek' origin, that there are crocodile men living during the reign of cleopatra, that tigers live in China and how the afterlife looks like...

You should have seen Saturday morning TV in the 70's, back when they had "children's programming stations". There were awesome shows such as Isis.

But to be fair there was also [url=https://en.wikipedia.org/wiki/Shazam!_(TV_series)]Shazam![/url]; from what I could tell both shows tried to hand down some collective wisdom.

Just so you know, it's the "Honest Hearts" DLC, though I don't remember what it's called in the quest log.

Expeditions Conquistar features many references and characters of the christian mythology. There are priests and charater perks that influence how their react to happenings.
The curious expedition has missionaries, christian I think.
Although both aren't quite medieval or fantasy

Aren't all religions fantasy? :^P

Diablo 1+2, though religion is never really mentioned, fighting the forces of hell is pretty religious.

Throne of Darkness, basically a partybased Diabloclone set in Japan, again religion is never mentioned (AFAIK) but it has influences of Shinto.

And last but not least Jade Empire, like ToD it's more Budhism mixed with the old local religions which is common in Budhist countries

If you happen to be interested in tabletop RPGs, Ars Magica fits the description - the setting follows roughly the same rules as Darklands (Christianity is definitively shown to be true, mythological creatures and fey are real, etc) though with a bit more magic than Darklands.
