It's not an action adventure, nor even a platformer, so spending 6+ hours purely looking/reading/standing/watching/completing challenges at your own pace doesn't apply here. A 6-hour Zelda-style game? Well you're lucky to fit 2 dungeons in that time frame; not genre appropriate (oh lol, that disappointment was called Beyond Good and Evil). Then again, I can beat Ocarina of Time in 6 hours (lol, not appropriate for the experience), REmake in 2 hours, and Mega Man X followed by Mega Man X2 in less than 1.5 hours total. This game length business should be put into some perspective.
But 6 hours of flesh-pulverizing people-killing? (and an impossible Hard Mode?) Wow. Even House of the Dead Overkill was a feat being a 4 hour don't-you-dare-stop-shooting adventure in original stages, plus a nifty stage remixing-lengthening Director's Cut. In contrast, Ghost Squad is a half-hour in one zippy playthru and Umbrella Chronicles is mostly recycled environments with slow traversal and winding, backtracking pathways (with quite a bit of forced replay to restock ammo/upgrade weapons and get better ranks to "unlock" the rest of the stages in difficulties OTHER than "easy").

Hard Mode intrigues me.
