I haven't played it in years, but man that was an good (addictive) game back in the day. I remember plenty of "oh crap, it's 3:00AM and I have school in the morning" nights.
Nineth on my server to hit 99 after Lord of Destruction... looking back, what a waste of time that was. Firewall + Nova Sorceress for the win. 😛
I think it was the loot system that really kept me glued to that game. The PvP was horrible, classes were pretty boring after a while, and bosses were a joke. The loot tables and trading were tons of fun though, minus all the duping and other exploits.
I dusted the game off a while back just to see if it would be fun again. Getting used to 800x600 wasn't easy. 😛
