We've been poking around with War Engine lately. The rules are very simple, but there are several "gotchas" you have to keep track of in character generation. So, I made an online character generator. It's still fairly rough-- there are certain legal characters you just can't make yet, and I'm not checking for every single gotcha, but it's still a real asset when creating troops. If you find a bug or are missing a feature you really need, let me know.
