Super Mario Land for the Gameboy. It's still one of my favourite games. I lost it at one point and had to buy a new copy off eBay, just so I'd know I had it.
No words needed. (unless no-one has any idea what I've just posted; it's Chip's Challenge from way back in 1989.)
The best game ever created is Monkey Island 2: Lechuck's Revenge, from 1991. The second best is The Secret of Monkey Island, from 1990 (yes, back in those days sequels were actually better than the originals). Final Fantasy 9 is also a very strong contender, but it's only 11 years old so it doesn't count as old .
Hm. Video game: Tetris...second Mario Bros. for Nintendo. Board game: Upwards, Scrabble, Sorry, Monopoly...Candyland. Card game: Uno.
Ah for sure! My little brother and I would spend hours making different roller coasters... funny how we remember little things like that.
