Not everyone likes history, but there is definitely a niche for historical games. Why not the areas of history covered by the bible?
Since a major part of the Bible is history, and it is the single most debated and verified group of historical records we have, not to mention one of the most well-read and well-known portions of history, with people reading it across the most ethnic, cultural, and geographical boundaries, to ignore it just because you don't like it seems pretty silly.
No offense, but this is ridiculous.
First: History games are popular because they tend to be alternate history - that is, you can change the outcome. They aren't linear. No Christians would be OK with alternate Christianity games that care about the genre in the first place. Job doesn't kill his son! God loses the bet! would never be acceptable. Luxemburg conquering Europe is quite possible in Europa Universalis, or rarely Victoria or Hearts of Iron.
Second, the Bible is rarely if ever used as a historical source. It doesn't cite sources anywhere, and tends to use both an abstract and personal concept of 'God' to explain everything, which is not a verifiable or reliable source. You bring up Exodus in particular, which is one of the least verifiable parts of the Old Testament - there is practically no evidence that suggests that anything in Exodus happened (there isn't even any evidence that the Jews were ever enslaved by the Pharaohs, even), and certainly not in the numbers suggested by the Bible (Sinai simply couldn't possible support that many people, and there's no evidence of a migration). The Bible is not evidence for itself, and lacking evidence other than the Bible, it is ignored by historians in general, particularly the more fantastic (using the original definition of the word) parts.
