Shame that I nearly forgot about this topic. I was expecting it to be more popular for some reason.
Here's some new stuff that I found on YouTube.
Here's a scene from Melancholy of Haruhi Suzumiya with Phoenix Wright music in the background. The first time I saw this scene in the anime, I didn't play any of the Ace Attorney games so I had no idea that the whole scene was a parody of the games. Now that I've played some of the games though, I find this scene to be a lot funnier. The addition of Phoenix Wright music makes it more laughable. You may not find it to be as humorous if you haven't played any of the games before, though.
Here's a pretty awesome gameplay video from Resident Evil 5. These two guys fight and defeat Wesker on Veteran difficulty (the "Hard" difficulty of the game) using just a bunch of flash grenades, rotten eggs, and melee attacks while taking no damage.
