as a kid i remembered my digimon turning into either numemon or sukamon
then i be like "fak this" and just proceed to leaving him hungry and die
also the first time my agumon died i was quite saddened by it
later older i knew more or less how to play it, think the furthest i went was that ice area.

my fav was Digimon World 3 and 2 tho (on ps1)
