Awesome, thanks. It makes a HUGE difference to the gameplay and how important your starting units are if you increase the recruit cost of units.
It's probably not going to happen, and I don't know if enough people are interested to make it worthwhile, but I wonder if it would be possible to add an custom difficulty setting to the 3-Chapter Story campaign that includes a subset of the advanced options. Not everything, only the Recruit cost multiplier, Starting Recruits, Dragon Spawn Cost, Recruit Rate quantity.
It would really make having the right unit mix important if you couldn't just save the day with the Dragon. The war would go back and forth more, and it would be easier for people to micro because there would be fewer units. I think adding that option in would reduce some of the complaints about "you can just spam blobs to win" and "The Dragon will beat odds no matter how poor", or at least give those people someting different to complain about.
I'm definitely looking forward to improved AI and different scenarios.
Right now I'm trying out "Recruit Cost multiplier" of 2X and "Starting Recruits" of 70 - which gives you just enough to let you build one Battle Forge and one Recruitment Citadel before having to rely on a slow trickle of income.
