My request (That isn't really a request, cause it won't happen lol):
Instanced Zones
My input on various systems:
Hair layer - I think this should be in the base system personally
Percentage-based damage/healing on spells - Would make sense as a base feature
Change HP/MP/Stat Points via Events - I agree with this
Events can combat - This is actually better if you simply summon the npc after the event has run (With instanced zones it makes sense)
Cast spells from events - The issue is that an event doesn't have any stats. Still, you can do dmg with events & use animations to get the same result. (As far as i know)
Recipe Books - great concept and something we hope to add to Nightmare after source release
Mini-map - I think having this in the base engine (as an option) would be great, but we'll likely see it as a tutorial
Tags on player names - An easy source edit (Not much point doing it now)
Player input - This would be good for puzzles where you need to input a code or something. An easy edit I would imagine.
a Built in system that can communicate with API for membership features - Members being able to trade with non-members makes sense actually
Penetration on projectiles - Cool in theory, but also a fairly easy source edit
On kill common events - It would add some, but not enough to warrant a change now
Upgrading damage formulas - Seeing as every game will be different, I think this would be better as an edit
Server Events - Awesome idea imo (Who's gonna do the tutorial? haha)
Pixel based movement - Will take ages to rewrite the engine, plus its not exactly superior in a 2D setting
Guilds anything - This will be great as a tutorial POST intersect 1.0 (Will present common syntax to beginners)
Movement speed and attack speed difference - This is possible without seperating them (Would just need a check-box for it in the spell & item editor)
