I like it. The item redistribution and unit distribution makes for a better flow for Impossible modes.
I already feel the addiction returning, after a large hiatus from King's Bounty AP.
I also like the replayability for the two shorter campaigns. It condenses the best parts of King's Bounty AP, and the extended version of AP's original world has gotten be back to the mega addiction due to the new spells and unit revisions.
I'm able to do a few more nifty strategies now with the subtle changes overall.
