Seriously, he's simply not worth getting into a debate with. When he first posted on his plan to get FS3, I actually defended his right to develop it as he saw fit... right up to the point he started calling the FS2 community a Cess-pit, and insulting every member of it.
He showed his true, childish colurs then, attempting a reasonable discourse will, every single time, result in the DS equivalant of 'I'm best! I'm best! Nurdy nur!'.
He'll thow insults and act in a generally immature manner, but that simply advertises who he is, it's the only way he can get attention, it's like Jack Thompson in that respect.
Ignore him.
