I may not be responding to everything but I AM reading everything and find the info very useful. So, thanks!
Keep in mind that a lot of these ideas/suggestions, like PK and death penalty, can (and will) be figured out later so nothing is really set in stone. Even major items, like perspective, that I need to decide now, can be changed if they just don't work after a release.
Also, don't know if I mentioned it but the RPGWO Community's involvement will be critical to the success of V4. I recognize that through your ideas, suggestions, play testing, bug exploiting, texting my phone, etc., it all adds up to motivate me to keep with the project. That was why V1/V2 (and V3) got so far.
It isn't gonna be that much fun during Alpha stages because of constant changes and wipes, etc. So, I'll probably add a /XP <skill> command so players can really experiment with the features. We'll see. Gonna start coding this week!
