What the hell are you talking about? Remake the game from the source code? Why? The games are still available in full, there's no reason to remake them on the same engine.
Are you even a programmer? Do you know what you're talking about? Because I am, and you don't make any sense at all.
I think he means Valve's Source. You know, the one that powers HL2.
To which I offer this response to the OP: Ha Ha, very Funny, But April was like almost 6 months ago.
If there's going to be a FP remake, why use source, when most of the hard work in the conversion would be avoided by using, well, the same engine that powers Fallout 3 / oblivion
