I'm depressed. I'm already dedicated to buying this damn game. I hope there is mods or something to make it last longer.
I put hundreds of hours into d2, and only made maybe 3 characters. ok maybe a few more, but actual use, was only 3 chars.
as mussels said, the time spent comes from multiplayer. it is really hard to explain, but it is definitely not a long game because there is SO much content (there is a lot though) - it's a long game because you get addicted and can't stop.
just one more run, that's all. i might get that awesome sword, or helm, or shield, or ring, or boots, etc. just one more run, i'll get enough xp to try that new skill. just one more run.
and the 20 hours is if you play solo and do nothing but bang out content the whole time. i highly doubt you will have beaten act 5 normal in under 20 hours, and once you do beat it that's only a 3rd of the game - you play nightmare/hell to get more skills to try, and better gear to use. there's still more new stuff to experience, but the main story will be over. it's not just replay for the sake of it though, you will actually want to keep playing into nightmare and hell, as it does feel different. monsters are harder and smarter, and it takes different combinations of skill and strategy to survive at later levels. that's where the real fun starts
i would look at it this way mm, if you only put the 20 hours in, then you lucked out and didn't get addicted to a game that most people will lose the next few years to
