Well, The Last Remnant and Infinite Undiscovery are prominent ones.  I mean, they saw how the Xbox 1 performed.   I forget which one came first, but I think it's Infinite Undiscovery.  So that came out, and did...okay.  Why when The Last Remnant came out would you not just put it on the PS3?  They had to see how the race was going there by that point.  And there were other companies.  There's only two options, SE wanted to create a niche for their games on a new unused console with a history of fail in the region, in case it picks up some steam.  But wasn't it worth the effort at that point to just make it multi and double the sales at the very least, if not triple?  I just think it's plausible because MS needed an edge in the region, and what better way?  

Infinite Undiscovery was originally being published by Microsoft, so its no wonder that remained exclusive. SE took up publishing rights, but Microsoft kept the trademarks(or so I believe, this I'm not entirely sure about.) The Last Remnant was originally going to be on both consoles, but when SE saw how it was a critical failure (I'd also go as far to say commercially too) they all but cancelled the PS3 port, as they knew nobody would buy a port of an already bad game.

They did see how the Xbox 1 performed, and the 360 has already outsold it in Japan by a few times, though that really isn't saying much. But outside of Japan the 360 was already doing far better then the original Xbox-- especially in the United States. SE wanted a part of it's new western fanbase, as it had grown quite large. Don't forget that Wada believed that the Japanese game market and development was basically dying and SE's focus should shift to the West more then it had in the past.

EDIT: Okay, yes, Microsoft still has Infinite Undiscovery's trademarks: http://www.microsoft.com/about/legal/en/us/intellectualproperty/trademarks/en-us.aspx

Just throwing this out there, but isn't the current problem right now in Japan that the major publishers outside of Capcom failed to put games on the Wii or PS3 and made a bunch of exclusives (timed or otherwise) on the 360 only?  I mean from before Tales of Vesperia, Star Ocean 4, Trusty Bell (U.S. name escapes me right now), Ace Combat 5, all on the 360?  Why?  What good did that do Namco and Square?  Square single handedly killed Star Ocean with that timed exclusive on the 360.  I mean I'm not saying they shouldn't have been on the 360 but there's no reason a PS3 version should not have been made, get your sales in Japan first and then worry about the rest of the world.  Like, not disagreeing with you cause Wada probably believes this, but Japan's console state is all his and Namco's fault if you ask me.

But then why make games so Japanese oriented if you wanted Western success?  That doesn't seem logical.  They should have done more gamesthat hada shot in the West, no?

I'm not sure I understand the question entirely, but I think you're asking why would they make them so "Japanese-y". I guess it's because Japanese-y Final Fantasy games have always sold pretty well in the west; so did games like Tales of Symphonia, Kingdom Hearts, and Star Ocean 3 in the past.

If you're talking about location where the game is based in, The Last Remnant had a pretty typical King Arthur knights-kings-dragons western setting in it. Star Ocean 4 was practically the Japanese version of Star Trek, albeit with less William Shatner.

Tales of Vesperia was the most Japanese-y JRPG to come out around that time. Eternal Sonata was close, but it was ll based on a western composer, Chopin.

Did I get the question right? I can't really tell what you meant to say in that last line of text.

No you got it lol.  I guess there's just a threshold that you can't go past of "Japaneseyness" for success in the West.

Yeah . . . and it's really annoying because now Namco isn't localizing any of their Tales games. I don't know what happened here in the west, but we need to have a "Japanese-style" game revolution here or something. Too many good Japanese games aren't being brought over (I'm looking at you, Tales of Vesperia PS3, and you Tales of Graces f. Namco; you suck.)
