The titles of the user submitted videos have been shrunken down so that they're easier to read. The game name and system has been removed from their titles for viewing purposes on the game pages (but the game name and system still remain on the actual youtube pages).

This makes it easier to find a video since you can now see the titles of the videos. Before, each video's game name and system would take up most of the space which meant that you couldn't see the actual titles of the videos and if you could, it would be buried within the long video title and therefore none of the actual titles stuck out. I'll give an example of what I mean.

Before:
Tecmo Super Bowl 2014 (tecmobowl.org hack) (NES) -
After:
High Score Run

That was an example of a title that cut off due to the game's name being so long. Here's another example of a title that doesn't get cut off but the actual title is burried:

Before:
Super Sprint (NES) High Score Run by Davideo7
After:
High Score Run by Davideo7

It's pointless for the video titles to include the game name on the game's page when the game's page already says the game's name many times.

patar4097 : Yeah I plan to do something like that eventually.
