Recent shadow colossus we a remake almost nothing was retained from the original and everything was remade other then music. Similar to how they don't remake scenes in a movie from scratch when they remaster it.I hate when studios use the word "remastered" when what they mean is "recompiled the code and made it run at a modern resolution"
The recent Shadow of the Colossus is an ACTAUL remaster.
Running the exact same art assets at FHD can be done on an emulator.
I'm pretty excited for this, as I played Shenmue on my DC back when it launched and loved it. I was pretty upset when the DC died prematurely, esp. when I was really excited to play the Shenmue trilogy on it, as well as Half Life (which I think even went Gold, but they didn't ship it still, which baffled me). I never owned the original Xbox, so I missed Shenmue 2 on it and don't think it was on the Xbone's BC list last I checked.
Since it's not a remaster or anything, I would hope the collection would be $30 or less though at launch. Also, I hope they really improve the load times at least moving between areas; I remember them being somewhat lengthy. But I'm sure just moving it to a HDD alone will speed that up significantly. The DC's old GD-ROM wasn't very fast by any means.
