For levels, we have the tiers. There is one new level introduced in T2 (compounds), and the monster AI is a bit different, but its still a rehash. In T3, there are zero new levels introduced, not counting FSC/bosses. The danger rooms are all the same for all three tiers as well... the danger missions are "new", until you realize that half of their level is a different level thats been recycled. The bosses are new and unique, but they each have a shadow lair that is again, recycled content. The
Every single weapon, barring winmillion/dark retribution/rocket hammer has a parallel line or five that function in exactly the same manner as the original design. Upgrades to weapons don't usually add anything new either, though this is hardly rehashed content and isn't something I'd harp on. Armor models are all the same way, with much of the armor in the game having entirely similar stats- dread skelly helmet, snarbolax cap, and kat claw cowl? Almost all armor models are copies of other armor models, but reskinned/reconfigured slightly.
Many of the accessories are all parts of various levels and models that have been recycled; e.g. the flower accessory came from firestorm citadel's D25 level. The dragon wings, Valkyrie wings and obsidian disciple wings all use the same general mechanism. These are from 3 entirely seperate promotions.
The battle sprites are relatively unique, with the exception of drakon, who is a stronger fire vial, a better fire barrier pickup, and ash of agni.
The guild halls consist of one or two new models, with many compilations of existing items thrown into the mix. Some of the items are existing models that are now being sold to you for 50 dollars; like the zombie bellhop.
What's wrong with being Green?
