Sonic 1 Ad - GHZ1, player gets 1up with 50 rings; LZ, small portion of lower, removed background is shown (I also think SLZ might be lacking BG scrolling).
Sonic 2 Ad - Beta title screen (they changed it REAL late, didn't they?) with menu, BLAST PROCESSING (<3), slanted CPZ corners, et al... Anyone else notice anything different with this one? Someone try and get a look at the split screen to see if it says Tails or Sonic... I can't tell.
Interesting stuff... Any ideas, guys? I'm guessing these ads were both made fairly late in development, so we may be able to figure that these differences were stripped at the last minute. LZ's lower background in particular intrigues me - why remove it? Looked pretty hawt to me (maybe it was a mistake from the vertical wrap? Or had they already decided on changing a majority of the BG? Who knows). I can figure why they changed the 50 ring 1up, though - it's way too easy to obtain.
What about that elusive beta S2 title screen? It's shown up everywhere - the manual, a strategy guide, Nick Arcade... hell, even TV ads now! (was this ad running after the game was released?) Surely there has to have been SOME important, vital reason for it to have been changed last second, shouldn't there? Issues with whoever sprited the original title screen art, maybe? It boggles the mind.
