Gaming wouldn't be what it is without this
Donkey kong Jr.: Better but this was my least favorite.
Egg: The best starting game, easy to start but quickly becomes an entertaining challenge.
Green House: Okay but the dual levels take away from it slightly.
Mario Bros: Another good simple game that becomes more difficult and gets better as it does.
Turtle Bridge: Another good game that is the spirit behind the Game and Watch series.
Like 2 Game and Watch 3 has a good number of stuff to unlock, and thats really the point of these games, to unlock things that will keep you playing longer.
