Out of This World (Genesis) Game Play
Out of This World is one of the most unique adventure games that were made because it required you to think about the order in which you do things. While I have never beaten the game from start to finish, I've managed to get as far as the part where lasers are constantly blasting behind you as you're running away.
I originally played this game for the SNES at a friend's house one night on a New Year's Eve. I stayed up until about 6:00 AM playing this game. A short time later, I found out it was being released for the Sega Genesis, which was cool. One of my other friends got the game for his Genesis, so I was able to borrow it from time to time. Eventually, I ended up being able to get my own copy.
There are some differences between both versions, mostly in terms of music & sound effects, but the Genesis version is the one that I'm most familiar with. The guys on the Console Wars channel should totally do an episode on this game for both SNES & Genesis.
