Sonic Boom is a borefest, so I'll vote for that.
sonic boom
also all versions of SA are bad. the game sucks ass but people just won't accept it because their judgment is clouded by nostalgia
Honestly SA is a strange case of a game for me. Yes it hasn't aged that well and yes it is pretty flawed, but I still like the game because its fun. I always had minimal problems with the camera and controls and I never ran into any glitches. Its kinda a guilty pleasure in my book, but my experience with it has been pretty smooth.
Swamp is right though to an extent, the original SA doesn't have as many glitches as the remakes and ports after, but it is still pretty damn glitchy.
