Mohammed?
You must have a death wish to have even implied that.
Literally even depicting him let alone fighting him gets you beheaded.
We all know exactly where SSM is, after the first trailer drops the studio goes up in flames.
Lets not even try fanning that flame.
P.S You could totally do a "christian" god of war cuz a bunch of Angels actually fuck shit up, and christians arent too fused about have Angels and whatnot fighting.
Realistically and stylistically Id say lets go
Egyptian.
The Egyptian pantheon has a ton of Gods who would be able to put up a good fight.
Heck, id say we could even go
Celtic and have a good romp. And have some interesting accents.
Something interesting and a bit different then use the Hindu gods.
Want to really have fun with a very open pantheon then we go really old school and do
Mesopotamian.
Any excuse to have another depiction of Gilgamesh.
