I saw this topic a while back and didn't pay much attention to it, but I think that I could write some articles/guides (despite my past history, I do actually time attack some levels, though generally only the shorter...levels).
As for videos, I think that most of what Nintendan is suggesting is a good idea. For the compilation, I think it would be interesting to TA one zone per game for 7 games (or 8 if we want to complete a final boss fight) and submit that. For extra Sonicyness, we could collect one emerald per zone. To clarify, the video might include:
Sonic 1-Green Hill Zone
Sonic 2-Chemical Plant Zone
Sonic CD-Tidal Tempest
Sonic 3-Carnival Night
Sonic & Knuckles-Hidden Palace (and maybe Sky Sanctuary to keep up the pattern of 2 levels per game)
Sonic 3D Blast-Gene Gadget
Sonic Advance-Cosmic Angel
And now is where things get interesting. If you noticed, all the games are in chronological order of release, the zone ascending by one. For example, Sonic 2, being the second game in the series, has its second zone as the level played (though this is not the case with some of the later games, as their corresponding zone is based solely on what order they are mentioned in).
With the 7 zones covered, we need to worry about both the extra zone and final boss fight, should we so choose to do this. This is meant to show the evolution of the Sonic series through the years, and how it has changed, so it only feels right to somehow include Sonic Adventure 2 (Battle) and Sonic Heroes. I say that we include Cannon's Core and Biolizard from Sonic Adventure and Metal Overlord from Sonic Heroes. However, if we did this then Sonic Rush, considered to be of some importance in the Sonic series, is excluded. Unless we were to scrap some of the minor games such as Sonic Advance, which isn't really known for much. If we were to do this, then the vidded zones would look essentially the same. However, here we would have to decide between a few different games with zone 7. The potential candidates would be Sonic Advance 2, Sonic Advance 3, or Sonic Rush, though we break sequence here.
Unless we got rid of Sonic 3D Blast, in which case another zone is freed up and we possible omit SA2:B for Sonic Heroes for zone symmetry, allowing Rush to deal with the extra zones, though it just doesn't feel right to ignore a game like SA2:B alltogether.
Or maybe we could loop back to something of note, such as Death Egg Sonic 2 (first Super battle) or S3&K (an epic showdown, truly)
Obviously, someone would need to supervise the project, should we decide to do it, and I suggest Nintendan, RPG, Sprint, mike, douglas, SM, or someone else, preferrably well-versed in the older Sonic games and with "leadership characteristics".
If you don't feel like sifting through all of my post, here are the proposed games/zones (extra zone and final boss fight not covered)
Sonic 1-Green Hill Zone
Sonic 2-Chemical Plant Zone
Sonic CD-Tidal Tempest
Sonic 3-Carnival Night
Sonic & Knuckles-Hidden Palace (and maybe Sky Sanctuary to keep up the pattern of 2 levels per game)
Sonic 3D Blast-Gene Gadget
Sonic Advance-Cosmic Angel
Perhaps each player who vidded their run could later add commentary to give it a more personal feel.
Oh, and I suppose I'll write some things up. Do we just give them to Rolken to submit?
Edit: Gah, just looked at the dates. If this is over, then my mistake...
