"Wondering why its 1.5? Because I have made too many updates for it to still be considered part of the original v1 client, but there aren't enough updates for it to be a whole new version, v2. So its v1.5!"
Like what exactly?
New 508 npc's - Already in the client
Many new interfaces - Already in the client
Many new objects - Already in the client
Much less lag - Didn't lag anyway >_>
"The new customs are never before seen, models, made by Darkdeity, and myself.
Examples: Blood Legions armour, War Wizard armour, Twilight set, Holy set, and Gilded dragon!"
Orly? Which did you make?
"Many new items made by me, such as, "The Straight Edge," "Fury armour," and some customs made for other players, such as "Xbosx's Mask.""
9 isn't many, and they're called recolours if you used an existing model fool.
