Yono is a short but very cute isometric aciton/puzzle game. It plays a little bit like a 2D zelda game, if you removed all the items you can equip and also made it more puzzle focused. The puzzles in this game are very easy though, so this would probably be a game best suited for kids and people who are new to games.
The best parts of this game are clearly the cute main character, and the way people speak about elephants.

I had never played this game before, and was not even entirely sure what it was about. I knew about the whole rolling around an ever expanding ball of stuff, but I did not really know why or if the game even had a fail-state.

Katamari Damacy is a silly game where you roll around a ball. It starts small, but as long as you roll over things that are smaller than your ball it will grow. Each level has a time limit and if your ball is not big enough at the end, you lose. The game does get kind of dark when you start including animals and people in your ever expanding ball of stuff, particularly as they clearly don't want to be a part of it and run away screaming when you get close.

This game was fun, and I can see why people enjoy it, although it did not really leave me wanting more.

You know the drill by now, review at the end of the post!

Golden Axed is a 1 level prototype for a game that never happened. There was some controversy surrounding the release of this, as the key people who made the old prototype were not informed about it beforehand, and they had a lot of bad stuff to say about SEGA's management and the working conditions they had to endure while making this.

Other than that, there's not a whole lot to say about it. It's a simple prototype, you fight a few similar looking enemies and then it ends. Pretty decent proof of concept though. Had they've tightened up the hit detection a bit, and added more levels and enemy variety, this could have been a good game.
