I typed “Walkthrough” into my YouTube search bar and waded through the 1st 17 pages of results, which takes us down to 200,000 views per video.  ”Walkthrough” returned the results of any video with the word Walkthrough in either the title or description of the video.  This should be a pretty all-inclusive list, barring any games besides Ice Breaker that have a crapton of videos for 1 game (I just happened to know about the walks for those games, so I knew to check…  no one of the vids has 200k+ views).

The List: Game Name (# of Vids) – Total Views in Millions – Ave Views/Vid

1. Red Remover (2) – 11.4 – 5.7
2. This Is The Only Level – 2.8
3. Wake Up The Box – 2.6
4. Poptropica: Nabooti Island – 2.0
5. Cover Orange – 2.0
6. Use Boxmen – 1.8
7. Roly-Poly Eliminator – 1.6
8. This Is The Only Level TOO – 1.1
9. Poptropica: Big Nate Island – 1.0
10. Wake The Royalty (2) – 1.7 – 850k
11. Poptropica: Astro Knights (4) – 2.8 – 700k
12. Fragger (2) – 1.4 – 700k
13. Poptropica: Spy Island (3) – 1.9 – 633k
14. Demolition City 2 (3) – 1.9 – 633k
15. Poptropica: Counterfeit Island (4) – 2.2 – 550k
16. Poptropica: Mythology Island (4) – 2.0 – 500k
17. Demolition City (2) – 1.0 – 500k
18. Crush the Castle: Players Pack (4) – 1.3 – 325k
19. Stadium Sneakout (10) – 1.0 – 100k
20. Ice Breaker (40) – 1.8 – 45k
21. Ice Breaker: Red Clan (40) – 1.4 – 35k

These are video groups done by 1 person; no mix and matching.  Also, no 1 game/island had more than 1 person with 1 mil views on their walkthrough… although 1 or 2 of the Poptropica Islands were close with a 2nd.

Analyzing the list shows very specific types of games that meet this list: Poptropica, Phuzzles, and Puzzle Platformers account for 19/21.  CtC:PP is a physics game, but not a phuzzle… and Stadium Sneakout is a point & click that doesn’t really belong on the list at all because each video is :08-:30 long.  The top17 are 6 Poptropicas, 8 Phuzzles, and 3 Puzzle Platformers.  Finally, I made 8 of the top 18 (8 of 12 if you discount Poptropica).

If you know of any game that I missed, please let me know.  :)
