Having a blast with it so far - I'm enjoying it so much more than the other TW games. It feels a bit more 4x-y than the other ones too - I feel as though I've got meaningful stuff to research and build, and more RPG like advancement on my heroes.
It's got a few wrinkles obviously - I got an incredibly annoying few turns when an ork hero kept on sabotaging me so I could barely move my main hero - obviously it was some sort of RNG madness, but it was just painfully annoying. There was no real reason behind it, I just got a bit stuck for a few turns until they eventually decided to run off. Similarly, sometimes the AI just seems to fluctuate between being painfully inept and masterfully homicidal.
As for mods, I got the home region movement mod and the skill number booster, and it seems a pretty good combo. If anyone's reading who hasn't modded it, I feel they're musts.
The DLC thing is pretty awful - but it's to be expected I suppose. They obviously feel that they've hit the nail on the head with the 'see what you could be playing with!' idea, but it just makes them come off as bigger money-grabbing wankers than usual. Doesn't detract from the fun too much, but it's annoying to click something and then it explode into 'OH THATS DLC IF YOU WANT THAT THEN YOU NEED TO BUY IT LET ME TAKE YOU STRAIGHT TO OUR STORE!'
