Really hard to unlock sqaut
Nobackround music on origanal games (they were kept exactly the same)
This is great for people who still remeber the G&W's.
But, if you just want a great collection of hits, you can't go wrong with this either.
It has some pretty addicting titles, like Donkey Kong Jr. and Chef, but some stupid titles like Donkey Kong 3.
The other negative is that it takes forever to unlock things. Mr. Game and Watch tells you that a star is earned for every 200 points. Get 1000 points in chef, and you only get one star.
I recomend it, but, you'll be very bored to earn all the exra games.
