Spoiler: Japanese ones tend to be better.
Which is odd, because I have the exact opposite opinion when it comes to, like, actual games. Sold Demon's Souls a little while ago, and despite loving the first Way of the Samurai like it were my slightly idiotic son-in-law, I can't fucking stand Way of the Samurai 3. I'm either not gonna review it or do so without a score, because I can't even complete the game once without getting frustrated and angry.
Slightly unrelated: I am so fucking sick of bad guys that take memorization and a high-level weapon to kill just because their attacks are really strong and they have a shitload of HP. If Way of the Samurai had the fighting system of Bushido Blade, it'd probably solve every goddamn problem I have with the game. If I wanna kill the recruiter of one of the clans midway through his speech, I shouldn't have to level up my sword eight times and bring a baker's dozen of mushrooms and rice balls to the table just to survive.
I really can't remember the last Japanese game I unequivocally enjoyed (Little King's Story was great, but did take some equivocation).
