Pretty sure these games are going to be handled by SEGA Hong Kong, which lead the PlayStation 2 re-release of NiGHTS.
LOL@DX being inferior.
It had updates graphics, models, textures, fixed a couple issues in levels, and made a whole bunch of fun glitches.
The graphics were updated terribly. Sonic's model fit in with everything else in the Dreamcast release, but in the DX one he literally had 5x more polys than anyone else. There were people walking on the streets who were just a touch heavier model-wise than Lara Croft was in the first Tomb Raider, but they were not updated at all, so it stands out even more in the worst way possible.
Someone like Big had a brighter texture and stuff, sure, but his fingers were more detailed than any other part of his body, and they never moved so it did not even make any sense why they did that.
Some models like Amy were obviously just built around the original, and because her head size was changed her eyes would sometimes sink into her head (I think Knuckles had the same problem, they probably all did).
They were also way too shiny now for some reason. Tails was so shiny he was practically
glowing white even though he is supposed to be made of fur.
Characters like Gamma and Robotnik were remained unchanged, when especially Robotnik was comically terrible looking for the time. I mean he was barely acceptable for 1998, why would they not even slightly alter his animations?!?
Not even going to go into detail about some of the levels being altered for the worst. They are really insignificant changes to art and sounds to what should have been easy fixes for the level layouts. There was also a lot of new problems like slowdown and control issues that just boggle my mind...
They even removed a lot of the extra options and sound test stuff! The only thing that really made it not a complete waste of money in comparison was that they added all of those Game Gear titles, which was pretty cool, but because they will surely not be in the XBLA/PSN releases... I could take or leave the mission mode, but it is nothing special.
