This being gaf, I expect a larger than expected number to say he's right. But it's a ridiculous statement and shows just why Japan has fallen so far behind. The gap between western gameplay and Japan gameplay is tilted in the west's favor by an even larger gap than the graphics gap.
Sure, Japan has a number of franchises that aren't outdated and horrible (and can compete with anything the west can throw at it), but they're certainly no leader in this category.
See, the problem is that "outdated and horrible" only applies if you like to push A to awesome and want a pass on actual winner-loser gaminess, and he's saying... That Japan tends to build around winner-loser gaminess and the US tends to build around chances to push A to awesome.
Of course there's exceptions on both sides and times and genres where you can flip it around, but as a general trend he's damn right because mainstream, AAA American development has gone off the deep end compared to anything else, Japan, Europe, or the same companies' products a decade ago.
Edit: Shit, I'll even say within patch levels of individual games. Terraria, for example, is an American game that I have played the everloving shit out of.
Before the most recent patch, it was an indie game churned out on a quick budget and built around a fun, addictive dig-hoard-upgrade-dig faster mechanic.
After the most recent patch, lots of branching endgame content and chances to be flashy-awesome were added.
My group tore through the first part of the endgame content, which involved digging more and hoarding more to dig even faster.
But the actual new boss fights? The chance to take down monsters with 10x more HP and glowing robot body parts using weapons that did 10x more damage?
Meh, we ended up restarting. Repeatedly, every time we got to that point.
