(No offense to Sonic 06 fans, and I didn't like this game, just saying.)
1. I needed to say this first, you can't even jump and kill enemies anymore. Seriously? No mais jumping and touching an enemy to kill them anymore? ISN'T THAT ONE OF THE THINGS THAT MAKES SONIC SONIC!?
2. Every character moves at the speed of molasses.
3. Mach speed sections!
4. Terrible vehicle sections!
6. Absolutely atrocious voice acting.
7. No jumping after the spin dash.
8. IT'S NO USE!
9. Terrible boss fights!
10. Soleanna was a boring, too large and confusing, and most of all bland hub-world.
11. Pointless missions, like playing hide n seek with kids, and walking a freaking dog.
12. Awkward looking NPC's.
13. Silver had so much potential but the way they used him is so insulting.
14. No auto-save.
15. Laughably terrible glitches.
16. WHAT DID THEY DO TO EGGMAN!?
17. Way too many characters, therefore creating problems with making each one unique.
18. Silver in co-op is broken as hell, he can literally throw you off a cliff! GREAT TEAMWORK! :D
19. TAAAAKE THIIIS!
20. The load times. Oh god the load times.
(And so much more, but let's not take forever.)
1. THIS IS A GAME WITH (Mostly...) NO TIME LIMITS! ^___^
2. The music, like always, (Except in Sonic Boom. D:) IS FANTASTIC!
3. I don't know how, but you have to amor the game just for how bad it is. Specifically when Sonic falls right through the surface, and when he gets flown into o espaço por Silver... Somehow. :D
4. So many characters is also a positive, it's major fã service.
5. Still a better amor story than Twilight. :D
6. Silver (NOT IN THIS GAME....) Is a really cool, epic, inventive, and awesome character that was introduced in this game!
7. It's just no use. :D (Have to amor that line, somehow. :P)
8. The graphics for a rushed VERY early PS3 and XBOX 360 game, aren't that bad. Actually pretty good, for the circumstances they were in.
9. His. World.
10. The final true boss fight was awesome, and the ending was also really good!
(And... A few others I missed. Hope you enjoyed!)
