So far it feels really really good. I like the new building chains and how it actually makes sense to upgrade a lot of things now and how the PO penalties aren't ridiculous at stage 3 and 4 anymore but kind of gradually get worse.

I've played a few turns in a Suebi campaign with a friend and I've noticed that I can now recruit all the DLC units, which I guess is a bug cause I've not bought any of the DLCs. I suppose this will be fixed in the full release though ^^
