Just played a few quick games.
Not bad, imho, but I really need to play some more to tell much.
Has the population of the countries been reduced? Because I seem to run out of it quite fast now, which is probably a nice way to prevent overly long, spammy RTS battles in the campaign.
During one campaign game I got repeated messages about the updates the AI had researched, did that happen because they had researched them before, or can the AI still research during the battles?
That was bugged in 128, at least, to list off all kinds of updates, from the Captain Obvious "The enemy can produce Troopers now!" to the outright wrong, as the announcer gave clips warning me about lots of things that absolutely no one had actually researched at all.
A lot of these increased buff lengths are really surprising. Cloaking is suddenly incredibly useful because it's fire and forget, you cloak and can feel confident that bar detection, they'll get into position before you need to cloak.
I like the decreased population from the previous patches, it helps keep the match times reasonable, and I like the higher research costs because now some things are really really expensive.
The change to reduce the Bunker Buster to 0 support is probably good because if you enter a map with too many units, you may never be able to use it.
