I dunno, I have always been really hesitant on using stuff from the internet that is not an official source. Mostly this is because the shit I run across is well. shit. (BRodda, I have seen what you have been posting, and this descriptor does NOT fit your work)
Most of the items I have seen have been, well, broken. Like psitols with 100rounds 11p -6 AP and use rifle ranges. (for example)
Also, the MMO mindset has definitely turned things around. Before a GM could create something and the table would fly with it. Now a Gm creates something, and the argument turns to "balance" and "fair" and "RAW" and all that other wonderful arguments.....
