Good stuff! Some of those things I remember... Spawning lots of invasions to attack the tunnels. That one was fun! Or absolutely destroying Harro during the final days leading up to the merge. I think I did that on Shadow or maybe Twilight.

Not an in-game thing, but we once had a reported bug about a quest.. I want to say it was a wishgiver one that gave +dex or something. We went and looked at the reported character and realized that the player had completed it over 2,000 times! It was only supposed to be able to be completed once or something. Bit of a shocker.
