Off-Topic:
I love Tactics Ogre. I have only played on game of the series so far (and still playing it), but if there’s an RPG I’d make, it would be very much like Tactics Ogre.
I strongly recommend Xenonauts. It has (imho) better field-of-view, cover and air-battle mechanics. However it seems a bit dry compared to the new XCOM by Firaxis, which features nicer graphics and cinematic action.
Xenonauts is more a simulation, XCOM more an action game. You should play both.
