I think the demand for realism in games is fulfilled,
Just look at the games who really get honored in the last time,
wasn't shooters in most cases.
We need NEW stuff, not stuff that already exists or already existed, triggering fantasy,
pushing our thoughts to other dimensions, beeing creative.
We need Original stuff, I don't care if it is redone from another game that did something Original, but it has to be unique, innovative or just epic,
WWII wasn't epic, it was stuff.
To be explicit, wars themself, are stuff.
or to quote something "The game where you build stuff".
