Alright. Based on what i've seen so far, Ares is very complex.
He isn't a main you can easily pickup.
Actually, his whole play style is revolved around reaction and counters.
It's too early to give a full analysis, but i'll try.
The reason he is the "God of War" in the game is because in order to main him, you must perfect the game in a sense.
You must know all the frames and how everyone plays in order to react. His "mind games" work to an extent. Not what I expected.
So in a way, he is the Shang(MK)/Mokujin(Tekken)/Seth(SF). It's not that his moves are imitations of everyone elses, it's the fact that you have to be like a Shang player.
His mind games aren't good enough. (Atleast for now)
He does have pressure though. You get in with a b1 then 22 then d1 then d4 or 33. You can mix it up.
He's very slow. You could think of him as a more combo-y doomsday. His combos are limited though.
In fact, he IS limited. His trait should be immensely stronger. His specials need 1 additional move.
I believe for a fact that he will be buffed. For his zoning, he can zone effectively with meter. Again, his trait isn't as useful as you think. His sword/axe disappears mid screen if you get hit. And the thought of having to use my trait for a juggle is ridiculous. (Then waiting 8 seconds)
He has potential. I believe I still underestimate him. Personally I think he does best w/pressure up close.
Everyone is saying "Oh, Ares? It's all about mind games."
But everyone seems to be forgetting, you cant play mind games on people who do not think.
Also, you can continue a string and juggle opponents with (ex)dd2.
