The Genius of Sappheiros:

This is a neat game that can be summed up as Undefined Fantastic Object meets Romancing SaGa. For People who are unfamiliar with Touhou Project: http://www.touhouwiki.net
As for Romancing SaGa, search for it on Wikipedia.

Touhou Sahouroku, Touhou Project meets Puzzle Bobble/Bust-A-Move:

While we're on the subject of Touhou Project, the ammount of flash cartoons based off of that series is obscenely low, and only a scant few of them are good. Besides, it's time for something different.

Rick's Adventure Legends:

Here's something that MaelstormM is currently working on.

Fortune Summoners:

A really cool RPG platformer.

Vanguard Princess:

This was made by one of the guys behind Street Fighter 3 with Fighter Maker 2002.

Psycho Dream:

A badass Super NES game by Riot Telenet and Renovations in the vein of Castlevania and Valis. This game almost got released stateside, but that got canned when Sega bought Renovations out. I credit Jonathan Wojcik for discovering this.

Popeye-The Tale of Teasing Sea Hag:

This is the third Popeye video game made, and was made by Technos in '94. In case you are wondering, this was another case of something almost getting a stateside release, but didn't seeing that Technos went bankrupt. Also worth noting is that this game has more characters from Elzie Segar's comics than the Fleischer brothers' cartoons.

That's all for the videos, tune in next time for "The Importance of good gameplay design."
