Please look through all of the other threads instead of posting what has been posted a million other times before. Let's wait for the shiny lock to come now.. Should be out by next year, and basically the layout of the site is new. Just look through the other threads please.
AG3 is the new version of the current Armor Games right? It is scheduled to be released sometime in early 2011 (subject to change). It is a complete overhaul on the system that we have now. The system is made completely from scratch, meaning there is nothing pre-made or made from a different company (the forums for instance is made by another company that escapes me--there is a glitch that makes threads 40 years old, when said company was made).
AP and Reputation points are new. Armor Points will be given to game-based activity--playing games, submitting highscores, posting material into AGi, all that jazz. Reputation will be given community-wise. If you post something in the forums, for instance, and you get your post voted up, you get reputation, based on who voted it up.
