I'm not saying it's not fun because it's not like the Genesis games. I just don't think it's fun in the least. I expect platforming in a Sonic game, not mindlessly switching rails and bopping on enemies.
I still say that Jet Set Radio Future had THE formula for a 3d Sonic. Sega had (and still has) the talent to make a great 3d Sonic game, but they don't use them!
- Replace JSRF characters with Sonic characters
- Make the environments whacky environments with great artstyle ala the Genesis games, none of this realistic bullshit
- Game already has physics implemented into its platforming, which is bread and butter of Sonic gameplay.
- Replace tags with special rings.
- Change fights so that they aren't enclosed areas, give the player multiple ways to kill an enemy like Mario does in 3d.
You got yourself a great 3d Sonic game right there.
