I don't play IK as such, although I've always wanted to give it a shot. I used to go to a gaming club, and we planned to all pitch in and buy some IK books to try out, seeing as a fair few of us played Warmachine, so we thought it'd be a good idea. Unfortunately due to lack of numbers, quality of players etc. said club ended up being more of a hassle than the fun it used to be, and now my friends and I have stopped going, so we never got to try the IK game unfortunately.
We did, however, make up our own system and play it in the IK world, which was quite fun while it lasted. Even just with average knowledge of the world from wargaming experience, it was a really fun setting and we all enjoyed it.
Maybe at some point in the future someone will consider getting the books so our roleplaying group (more informal now) can give it a shot, but it's never been a huge priority, especially with so many having a disliking/distrust for the d20 system. Sounds like it's pretty good from what you've said, though
