I was recently told about Et Futurum [after releasing FutureBlocks] and quickly realised that it isn't in the least bit good to be competing against someone else, especially when their work is way greater than what you could ever do (currently).
So what are you going to do about it?
I plan on making sure I'm not directly competing with Et Futurum by making my mod for 1.6.4. This way, the author of Et Futurum can have his for 1.7.10 and I can have mine on 1.6.4. Peaceful!
The direct download (Beta 1.1.1 for Minecraft 1.6.4) is found here.
