I haven't even found time to look at this thread in four days.
Interesting to hear a lot of people feel similarly about modern games. I am aware that there are some who thrive on mining achievements, and as Ed said, have enough time to play through a game even if they know it's kind of half-assed.
For me, current-gen games fall into these categories:
1: Good, playable, well made, offers nothing original, I could bother but should I? (Yakuza 3)
2: Original, playable, lacks direction, stuffed with padding, the repetition starts to wear me down and eventually I'm distracted by something more appealing (Bayonetta)
3: Just another competent FPS, Battlefield, Army of Two, The Darkness (most 360 releases, take your pick)
4: Genuinely gripping, fat free, exciting and absorbing experiences (Gears of War, Super Mario Galaxy, Sin & Punishment 2, and although it dragged its heels a little at the end, Resi 5.)
Even though 1-3 can be perfectly well made games which will please most, they just don't hold my interest long enough for me to battle through. I'm not adverse to playing a game that takes over 8 hours as long as it's gripping. JRPG's in the 16-bit era (with a distinct lack of cutscenes) used to feel far leaner and progressive than the cut scene injected, gilt laden behemoths of today, and as such I had no problems dedicating 30 hours or so to finish them.
I feel as though it's easy to see through a lot of modern titles after just a few hours play - you know where it's not going to take you for your efforts.
But as Taylor said, it's a catch 22, as most customers demand games with at least 10+ hours in there, even if they are padded to death.
