Alright. People complain about the difficulty of Prime 2, Prime 3 is supposed to be just slightly easier, difficulty helps make hardcore games. You have to be able to think about things to beat it, also helps hardcore. The controls. Like a PC. Hard to name a PC shooter that's not hardcore...least for me. That doesn't really affect Prime, though. Uh, not having minigames. Hardcore. That's right. The size. Six hours being 13%, huge. And that's actually through the game, not items. I'll think of more. Oh, one more. People actually like it. Killzone 1, not so much. Killzone 1, hardcore. Prime 3, better than Killzone 1, more hardcore. I'm just rambling now.
EDIT: Gears is tactical shooter, those are hardcore.
