Turn Based Combat.

I picked up XCom: Enemy Unknown yesterday, and it suddenly struck me that this is the first turn-based strategy (computer/video) game I've played in years.
They seemed to go out of style about a decade ago, which is a real shame, especially on the RPG front.
Two of my all time favourite games are Shining Force 2 and Skies of Arcadia, both of which featured turn-based combat and felt epic as a result.
But with action games taking a fore of late, everything just felt like it had started to become a rush. You never have time to savour anything anymore. The character designs, the music, the monsters, the setting. With a turn based combat you can take your time and enjoy it all, and, most importantly, when you fail you KNOW it was your fault, not a shoddy camera angle or sluggish controls.
I think that's why the last squad-based RPG I played was Final Fantasy XII, which introduced Real Time Battles. Don't get me wrong, it worked really well, but I just felt it wasn't as enjoyable as a turn-based system would have been.
I really hope that XCom is the start of a return in turn-based gameplay, for those of us that like to ponder our moves.
