As a certified Fan Boy of Privateer Press, I was less then excited to here the latest info on the Iron Kingdoms RPG line is pretty much... Nothing. Very sad. They have said they won't go 4e with the current GSL in place. I'm hoping the promised changes may change their minds, but I doubt it. I don't think the IK range brings its money in worth the effort it takes to produce. This is sad as it is one of the great things I like about the IK/WM world.
I like 4e, a lot really, and would love to see the conversion take place. Some intrepid fans are working on some aspects and storing them at Gobbernomicon, a wiki that is holding other odds and ends IK info. I posted my Farrow conversions for review on the site. It would be cool to start building the world from the ground up, but unless I win the lottery tonight, I don't see me having the time to do that. I'll add my two focus worth from time to time. I like the monster creation and the new monsters for 4e are realtively easy to create from the stats given in the Monsternomicon Vol I & II.
I've committed to running and IK RPG event at Nuke Con and WARMACHINE Weekend. I will use an adventure thread I've used before and convert a few iconic IK classes to fourth level.
Not sure if I'll ever get to test play before, Nuke Con, but I'll try.
My Fan Boy is bigger then your Fan Boy!
