10 years? Checks date for Days of Ruin... 2008.... yeah more than 10 years
Advance Wars was a great series to take on trips, as it allowed for some good pick-up and play a few turns, suspend and finish later type play style. In that sense, it's a good fit for a switch title.
I wish they would have included dual strike in this mix. The art style was the same and hadn't changed like it did in days of ruin, so it's exclusion almost feels like it's being held back as DLC. (edit: and if that's true, that *would* be a punch in the gut!)
But I agree, that while the game was pretty polished there are always a few tweaks that can lead to some subtle changes. Especially 'behind the GUI' changes. I hope AI improvements have been made, particularly for fog of war. I forget which one, but one of the titles had a broken implementation. Better AI could also mean getting rid of some of the cheap tricks they would give black hole's army to make them "harder". So refactoring some of those elements would be a welcome addition. Would I feel like S-Ranking a bunch of the levels again... probably not.
(edit: another improvement... more options for animation. Most of the time I played with them off because I like staying sane. But having an option to hold a shoulder button or something before hitting A to fire and seeing THAT particular animation because it would be satisfying ... that would be a nice addition)
