Sexy is one thing, the way the woman are represented is a different thing entirely. I do wish they would make a proper sequel to Red Faction: Guerilla. Loved that game.
I would say a lack of marketing, poor PR (like how we were told SR IV was basically a DLC pack turned full game. That's super and all, but it really makes the game sound half ***ed.), people preferring more serious things and most of all, NOT ENOUGH CHEAPY D.
Misogynist critics is one factor, why Volition is underrated. They simply can't accept sexy female characters in games.
Red Faction 1 remake for ps4 would be nice.
