oh dear there are so many to choose from and theyre all my favorites and i still find myself playing them
win commander 1 (single best space "sim" ever made)
monkey island 1/2 (some day i shall own a mt32 to play it properly)
descent (bought a voodoo mainly for that and i just obtained a db50xg solely to play descent)
stunts (sorry scavier but this is the best racing game ever made not even lfs does get anywhere close)
outrun (second best racing game ever made ... thank god for emulators)
and of course there are some i found out about in recent years that instantly became favourites
space war (can you believe how much crappier the 10 years younger pong is in comparison ?)
space taxi (annoying to death yet very addictive)
descent 3 (i knew it existed yet i never found it to be the least bit interesting ... until i tried out the multiplayer part recently)
uah you sound like my dad
the black and white photocopies everybody had ? ^^
that one is a classic just because of the music (and remember kids it was electrik and i who made you hum that tune all week long)
Oh, how could I forget. My older brother got a MSX when I had just started school, and I shall never forget those diamond games that he had: Penguin Adventure and Livingstone, I presume?.
