The ideas/suggestions/inspiration this page gives in regards to Mars (mythology) and how you might make a complicated deity for your campaign world are pretty great. I really like this page. That said, the actual factual information the page lists about Mars (mythology) is sort of wrong, I think. I'm no expert, so I could be mistaken, but my understanding is that Mars as the Romans worshipped him before annexing Greece into their empire was NOT a rapist or bloodthirsty. He was a god of duty, patriotism, and protection, with a minor agricultural theme due to his parentage and his role as stable provider, but was for the most part totally lacking in mythic tales of his deeds. Mars was originally a more or less just a disembodied ideal to be aspired to. Many of the Roman gods were like this in their earliest incarnation.
Ares, on the other hand, was a hot-headed, violent, sometimes craven, jerk from pretty much his inception in Greek myth. He was mostly a disruptive figure often doing immoral or unfortunate things throughout the body of Greek myth.
It was only after the Romans spread into Greece and were exposed to both the Greek's significant body of myth, and the Greeks existing habit of assimilating other's myths and gods into their own beliefs (see Interpretatio Graeca) that the Romans said "hey, we could do that, too". So they ported over the already highly-successful mythic tales of Greece and ran a "find & replace" algorithm to swap Ares out for Mars. (Take that with a grain of anachronistic salt.) This effectively rendered many of Ares disruptive traits onto Mars thereafter, but my understanding is the Romans still made some sort of distinction between their Mars and the Greek version. Like "this is the real Mars" and "that is what those silly foreigners think Mars is like. They're wrong, but their stories sure are a good read!" At least, that's my understanding of the situation. It's not like I was there, and I certainly don't have a degree in any of this. It's just a thing I read in a couple of books.
Anyhow, I'm not sure that distinction really matters in the context of this page. I may be just splitting ares here, if you'll forgive the pun. You could not know this factoid about Ares and Mars, and still get tons of cool inspiration for your game based on the version of things said on the page. It's fairly pedantic of me to even point it out, but seeing as how this page disagrees with some of our other pages on the topic, it seemed like a caveat worth at least mentioning in the discussion section of this page. So if anyone read several conflicting pages on this wiki and wondered "what the heck is actually going on with this Mars guy," they'd be able to dig a little deeper and get some perspective. The pages contradict each other, and I think it's the other pages rather than this one that get those finer points correct… but the broader point made on this page that "real-world myths and religions are complicated and nuanced, and mostly-good Gods can be still sometimes be kinda evil" is spot-on, so I don't want to excise those excellent bits from the page. This way we get the best of both worlds, as befits the subject matter.
