This is IMO what Falling Frontier is shooting for, big scale RTS/4X combo, but with smaller scale battles and ships not so easily replaceable. Pretty much as if Sins was just capship game.

Personally, i prefer how Sins is doing it, or better said, if FF doing it that way, i am fine with Sins sticking to its bigger scope, SupCom like approach. It kinda makes more sense as well, no point in big multi-planet maps, if you dont have enough ships to cover them.

I see moving turrets as a gimmick anyway. Sure, i wanted it too, but mostly cause it adds to the immersion, for the visual experience, not for its gameplay repercussions. 

just saying that tactical combat where turrets would matter more would make more sense in a game where terrain is involved. I mean tactical terrain, not strategic one. What Homeworld 3 is trying to do with addition of those megaliths.

On topic of FF, definitely one to keep the tabs on, if you like Sins. Could be possibly even better game than Sins II, simply on the grounds of being fresh and bit more differrent, rather than extension of older, well known game. I will probably still prefer Sins, but will definitely this one give a try. 

Fragile Existence would be another interesting choice, adding actual ground based gameplay, and then obviously aforementioned HW3. These are 4 games i am looking forward to this year. Hopefully they will deliver.

I suppose they taken that from SupCom, where individual projectiles were simulated too. And it really did. Not make that much sense as it was such a big scale game, that it rarely mattered. I mean with nukes and anti nukes maybe.
