The "generic" complaints make sense because so far the only major defining features of this game that set it apart from standard TPS gameplay tropes are its good graphics, unique setting, and... a QTE melee system.
Modern Resident Evil's "thing" is focus on co-op, score attack modes, weapon purchases and upgrades, and the stun->melee combat loop.
Dead Space has dismemberment and antigravity and upgrades.
Gears popularized and modernized the cover system as well as set the standard for competitive TPS multiplayer.
Mass Effect has class based upgrades, unlocks, and different powers based on class.
Uncharted has platforming and hand-to-hand melee combat.
Tomb Raider has... I dunno, platforming I guess. (not the best example, and I'm sure many would actually agree)
Sunset Overdrive has fast acrobatic traversal, superpowers and wacky weapons, and fighting hordes of enemies.
The Last of Us incorporates stealth and survival mechanics.
The Order has mustaches and letterboxing and really good looking leather and metal.
I'm sure that RAD has some hook in there that they want to show off, but they haven't yet.
My hope is that RAD has some interesting story or game concept that will demonstrate what differentiates The Order from other games of the genre. If the game is just 12hrs of what we just saw but with different guns/environments, it may still be a great game, but it won't "Wow" anyone.
