You can get Perfect Dark on X360 and KI on Xbox One. They're still dead?

Perfect Dark was almost 10 years ago, and Killer Instinct was only recently revived, so I was half right.

And? You can still boot it on X360, matter fact, I haven't played that game yet.

PD has to be rebooted in a different type of game that it was a decade ago.

Indeed.
Perfect Dark released in 2010 on Xbox Live! Arcade showed it had NOT aged at all well, not only in image quality (They tried to improve it! But it's like polishing a turd...), but basic gameplay mechanics.
When the game was first released however, it was an incredible ground breaking experience.

It's a shame, it could have been an IP that's as big as the CoD or Halo's of today, it certainly has the rabid fanbase. (I was one of them!)
It was actually the ONLY reason I bought the origional Xbox Once Microsoft baught RARE, sadly it didn't get released on that platform, luckily Halo came bursting onto the scenes anyway.

What do you mean by that? A game is considered dead when it hasn't had a game in a long time. For example, Viva Piñata, F-Zero, and Jak & Daxter are considered dead franchises.

Your list consists if Japanese-oriented games, while I'm talking about Western Nintendo gamers.

In general, Nintendo gamers don't like any game which is violent (COD, Darksiders, Assassin's Creed) or have any level of realism (Gran Turismo, The Sims).

Are they really dead? You think if VP, F-Zero and J&D get a proper release it won't sell?

Better question
What can MS do to appeal to Japan?

MS doesn't really need Japan audience.

You can never have too big an audience
