I loved this game when I was a kid!  I don't think I ever played the game straight through, instead I used the fancy cheat code and would hop all over the game enjoying the world with my favorite weapons.  I used that cheat code soo many times that I will probably never forget it.  Anyways, I don't know if its aged well, but it was a lot of fun back in the day.  The sequel has better graphics but its a worse game in my opinion, also the cheat codes are in normal English which is lame.
