This is a excellent game,is so addicted I've been playing for four hours. Is so fun to play it,nice graphic but you need a expension pak to play with it,I've try it without the expension pak and I can't start it,you need a expension pak to work it. Donkey Kong 64 is the best game man!,there alot of puzzle to solve and to save another kong buddy,then you can choose different kong too. GO MONKEY!!
