06, simply because people somehow think there's things worse than it even on a technical level. No sonic boom, while abysmal, was not worse than sonic 06. sonic 06 had loading screens that literally took up ten percent of the game time.
sonic 06 is annoying, it has some of the worst designed boss fights in the franchise, if you get a game over you're kicked back to the title screen, silver the hedgehog is as slow as molasses, the ball puzzle is god awful, the mach speed sections are bullshit, the story is god awful to a painful degree especially involving Elise, the dialogue has NO intentional value to it, there are mandatory time wasting side quests, OMEGA RUNS FASTER THAN SONIC, and to top it all off they had the nerve to call it sonic the hedgehog as if this were to be some crowning achievement worthy of surpassing the original.
I'm fucking tired of people saying any mediocre game is worse than 06. Hell I'm upset if you call a moderately bad game worse than 06. Unless a game is PAINFUL TO PLAY, DULL, DRAGS ON TOO LONG AND HAS ATROCIOUS CONTROLS/PHYSICS... it's not worse than 06.
