According to that thread, he's basically slapping together various OS code to do what he wants. I fail to see how that will produce a game that is revolutionary in any way.
I will get my RPG to market long before Grimoire comes out. And I've only done a few lines of code. Whats more, Duke Nukem Forever 2 will be out, before Grimoire comes out.
And 2012 is passe. I saw someone predict 10-10-10 is the end of the world. Because it superficially resembles binary (maybe if it was 10-10-1010, of 1010 1010. Or maybe 1-1-01 , 0101 1001). At least, I guess. The same was said about 9-9-99 too. All that happened was the Dreamcast came out.
And lets not forget 1-1-00 (Y2K before it was changed to 1-1-01 so consulting firms could get more money). I deliberately changed every old computer I could find to 1-1-00 in their BIOS... and got an invalid date error message. Nothing else; one 386 laptop lasted a year after that, until I replaced it.
The world will end when Grimoire comes out. That's my prediction. And no one will care (either about the end of the world, or about Grimoire).
