It's called "DangerZone".
What is it? It's a block-building-critter-killing game I'm writing from scratch. Yes, from scratch. I've gotten tired of all the problems that we (the modding community) keep running into with Forge and MC. There's too many. Too often. And so I've decided to do something about it. I'm writing my own modding platform. DangerZone.
The intention is to build a base game, with a wide-open, easy-to-understand, easy-to-mod, stable interface for modders. Sources will be fully commented and for everyone to see. It will be small, fast, and written in java (so its easy for noob coders!). Once the base game is written, I'll port OreSpawn over to it, as just another mod, so it will be optional, just as any other mod. I've been posting weekly updates as I go.. check it out to see how far it has come along!
