So they've been making games since the original Xcom, and except for the direct sequel, which was more of the same but somehow less, they were reputedly a bit shit. The simultaneous turn-based stuff doesn't work for them, or anyway it hasn't in the past.
I played Xcom for the first time about 3 years ago. Brilliant. Then i tried the most up to date of the spiritual sequels, which turned out to be awful. I'm not holding my breath for this, but i hope they get it right and find some of the original magic again.
