Sonic Unleashed looks good? Please, stop mixing art direction for technical specifics. There's no point talking to you TA so stop bothering to reply to me, you often either don't understand the terms of discussion or keep shouting the same points that are not in anyway either relevant or have been disproved several times.
I don't know anything about the technical side of the Hedgehog Engine, but Sonic Generations was fucking beautiful on PC maxed out. Perhaps because it was cartoony graphics, but it looks almost flawless.
That's exactly what it is, people are muddling art direction with graphics when it comes to Sonic Generations/The Hedgehog Engine. By the same virtue Mario Kart is a fantastic piece of graphical engineering and pushes the Wii U above the Playstation 4/Xbox One when it just is not the case, Nintendo, like Sonic Team and Ryu Ga Gotoku Studio (Plus countless Japanese developers) hide technical short comings behind excellent art direction.
When you stop and slowly inspect the scenery,
Sonic Generations has a lot of low poly models for a reason and the console versions suffered from horrible pop ups.
