I know the PCE is a very capable system and certainly was ahead of its time at its release, but some of the games shown in the recent screenshots really need to be seen in motion to appreciate more.
The one that caught my eye in particular is Secret of Mana 2, yes it looks great in these pics...But it looks far better in motion. the game is just a masterpiece for what the Snes could do at the end of its timespan and in competant hands [squaresoft]. Id wager that against any of the PCE or Genesis games it is being compared to in terms of animation, graghics and color.
Besides that I am admittedly a Squaresoft fanboy [of the snes games atleast...I didnt like anything beyond FF7 from them] so dont take my post as a knock against the PCE. I just find that Squaresoft's quality during the SNES's heyday was outstanding so its hard to compete with that. It would have been nice to see Square give it a shot like Konami did with Drac-X [great game and looked good to] that way a comparison would be more fair.
In order of Quality I would rate it like this for the last set of pics [page 50+]..
Snes-Secret of mana2>PCE LoX2> SegaCD pics [dont know the name of that game, popful mail?].
