I played it for 2 days, here is what I think:
I really like the unit variety, there is 6 infantry units, ~10 vehicles, 4 choppers and few planes, each comes with an upgrade or two.
Resource system resolves around finding fields with oil/aluminum/rare earth and put extracting facilities near them, then little trucks start traveling between them and your base delivering theextracted goods, if the facilities are far away you need to buy more trucks so the refinery doesnt fill and stops producing untll some room is made again.
There are also banks, which can be occupied by your troops and looted for steady cash flow, think of hackers from CnC Generals, and buildings that can be built that give you flat income like GLA Black Market.
Finally, some of the infantry units can capture wounded enemy troopers or pilots, they can be stored for later use in field hospital (For USA anyway) and sold for 1000 aluminum (Which is a lot, to go to Tier 2 you need 2000 Dollars and 2000 Aluminum) or 250 rare earth (Which is handy sum aswell, I don't remember how much exactly but ~500 rare earth will net you a nuke)
T1 units cost mostly Dollars, T2 Aluminum and T3 Aluminum + Rare earth. Abrams however costs only dollars so theywill be your main cashdump in the endgame
This ends up being a little hectic however, if you want to expand you spread yourself very thin, droping refineries all over the place, maps are very big, and units, especially infantry are very slow, so transport units are a necessity. Which leads to cosntant harassment cat and mouse, with you driving around and capturing (because marines can capture buildings, just like Generals) enemy refineries while trying to deny your enemy the same, WHILE defending banks from snipers and mortar fire WHILE capturing enemy prisoners and healing your wounded with medavacs.
Combat itself is, at least for me, a ton of fun, with large variety of units and ways to utilise them. Infantry feels ultra squishy though, a single mortar shell drops them all in its explosion radius, so taking cover in one of abundant buldings is necessary.
It is also extremely important to not fall behind in tech race because you'll get nuked into oblivion if you don't build yourself a patriot missile. Also if anyone was wondering then yes, game ends with you facerolling the enemy with gazzilion of tanks so its CnC allright. I wonder what are the other factions because mirror matches end up being a bit samey in the end, but its like every other rts.
As a bonus fun autists in chat crying that its not their Wargoim anymore
