EDIT: And tristriams theme song! that song is just awesome!
But when diablo3 is out, and 8 years old, and we will look back at Diablo 2, i will sure remember when i got ocu rings in 1.09, and now i hate the Battle.net-channel music, but someday i will look back and miss that music
Well, i can list the moments that were when i played for the first time this game, but...
I'll say the best moment with diablo 1 i had was playing a version which was translated to polish by drunken ukrainian who barely knew how to speak polish grammatically. The joy of discovering yet another hillarious speeches, which barely made sense, and also were dubbed by one man who pitch-shifted voices to fit into character was undescribable! I knew this game by heart (i dunno why but whole game except the warlord of blood quest... i never had it even though i played d1 dozens times...), but i could play on and on just to hear and read all the gibberish that spewed out of screen and speakers! Best. Gaming. Expirience. Ever!!
Playing Hide&Seek in Tristram with friends over B.Net.
Hacking in Map of Stars and hiding it behind Gillian's house, then telling a story about the Secret Cow level involving the Map of Stars to a friend of mine and then making him follow my instructions after which he thought the map 'truly' spawned behind Gillian's house, and I was like 'what? it worked'??? Fun times.
