I'm satisfied, but hesitant. There are a number of undefined terms now. How they are defined will have a large impact on what these changes actually mean for the game. Additionally, there are some rules changes that do not make sense, even when we ignore the ones that need terms defined. Inventive Scientists is now needlessly complicated considering you'll only be using one generator per turn anyway.
1) The new "wing" rules are simultaneously awesome and terrible. I have the choice between 5 fighters/bombers or 1, ONE, recon plane? If I want 2 recon planes, that is my entire allotment of tiny fliers for the game. That's pretty rough.
2) Land ships are still terrible. I'm puzzled at why the CoA and FSA ones got nerfed. Land battles are largely unappealing because the models are not anywhere near as efficient or effective as air or naval models. Either point reductions or more special rules are necessary to make them more appealing.
3) Every nation's new MAR/generator/whatever got slapped on the STAT cards except EBS. Do they not get sharp turn now? I'm left puzzled.
However, I love the new Core Force rule. Less fliers will make everyone happy. Seeing KoB get some more marines and the Guardian generator is awesome. I know Rick will be excited.
