As a LOOONG time AW vet, my early (~8 hours in) feeling is that the actual strategic gameplay might be the best found in the franchise yet, and that's saying a LOT. The new units and gameplay tweaks don't just feel "tacked on" - they really do change the dynamic of the strategy and give the game more depth. It's obvious they actually playtested all their unit changes for strategy and balance.
-Infantry costing more and mechs & bikes costing less greatly reduces the "Inf. spam" technique.
-The entire sea game has been completely revamped and barely even resembles previous AW titles (in a good way). Sea battles are more than just Rock Paper Scissors now.
-The Md. Tank TRULY being a medium tank and the addition of the War Tank spices up the mid-match ramp-up quite a bit. Do you build a Md. Tank this turn, or a War Tank next turn?
-Fog of War is actually a lot more fun this time around thanks to the Radar buildings (iluminates five square when you cap one), the Flare unit, more terrain that provides cover, etc. I used to hate Fog of War, and in DoR I've found myself really liking it.
-CO's being ON the battlefield is a bigger addition than you might think - they turn the tide of a battle, but it's a risk vs. reward thing. Do you send your powerful CO unit into the fray, or do you hang him back a bit, but still close enough that nearby units get the area of influence boost? Another GREAT strategic addition.
-Lots of other little things like Landers getting a price drop, sea units passing under bridges, etc. It seems like IntSys took a close look at balance for the first time since AW1, and it really does make the strategy just "feel" better. It's fantastic.

BUT, all that being said, I think the *package* is probably the worst since AW1.
-No War Room
-No Hard Campaign
-No Battle Maps/unlockables
-No Survival Modes (they weren't great, but were still a nice change of pace)
-No tags/rankings, besides on the medals screen (which doesn't count)
-Less CO's (I know the CO's have been de-emphasized, which is a good thing and helps the game strategically, but they still could have had more of them with unique influences).
So at the end of the day, the strategy itself is the best found in the series to date, but the package is pretty gimped.
Make of that what you will.
