ShowEQ

ShowEQ was a highly-banned third-party "cheat" program which allowed players on live to see all of the information the EverQuest client could see. This included a great deal of information that players wouldn't normally have, such as the exact amount of XP each mob gave, or whether a particular mob was up and if so where exactly and what it was wielding.

ShowEQ allowed players to learn a great deal about the mechanics of the game, and that knowledge was instrumental in creating Project 1999. However, that program has been banned here (and the ban is enforced by P99 software). In addition the ZEMs (Zone Experience Modifiers) on Project 1999 have been changed from live, to better simulate the fact that non-cheating live players never knew what the ZEMs were (but thanks to ShowEQ the live ZEWs are well known).
