You'll be surprised to find that Greg's the one doing backend and API coding, while the content changes are pushed by sfplayer and the other IC2 maintainers (though doubtlessly they asked Greg for permission).Apparently Greg is now a official IC2 dev and is bringing some of his concepts into default IC2 to breath new life into its undead corpse. Which is great as long as he keeps the hard core concepts in Gregtech and does not add them to default IC2. As I highly doubt that player or richardG would allow him to turn IC2 into a hard core only mod.
And in the real business world they already develop new products when their current one is at consolidation. Rebirth is just an extra money income :bI want to pop in and say something i found:
Ic2 is just like the butler model of tourism (picture below)
IC2 is currently at stage 6, where it either dies off or becomes a new.
Its really really funny, it fits in so perfectly xD
This wasn't Greg though, he's still only doing backend work..... so, all you folks who said that "him" wouldn't be allowed to make changes to the play mechanics. We get to laugh at you now.
