Brawl is a somewhat interesting new homebrew game for the Sega Master System. It mixes various known video games characters such as Alex Kidd and let you fight against other well known franchises. Also it takes backgrounds from Wonderboy and other games and mixes it up, which in sum makes up a nice gaming soup á la Super Smash Bros. The game is still in (slow) development and even Sonic is said to make his appearance in this game. Make sure to keep your eye on this project as it really develops nice.

This is a perfect example of what free, non commercial, fan games can look alike.

Tower of Sokaban by Killer Bean 2 and BG is a small demo of what will hopefully, one day, become a somewhat playable game. The gameplay is, as you could guess from the name, about moving blocks around.

You’re Derpy Hooves, mail mare. Spike’s ill, so Twilight Sparkle has asked you to fly her letters to Princess Celestia. But Gilda is harassing you! Fly around and press button two to drop an anvil on her. It’ll make her much more angry, which is probably not all that good of a plan, to be honest. Avoid getting hit by Gilda – she’ll steal one of Twilight Sparkle’s letters. If you lose all three, you have to return to Ponyville.

This is a very basic game with no real ending – it just gets harder and harder until you lose all you lives or it loops around and goes back to the starting difficulty.
