Xcom EU is great with controller. You can sit down and relax and enjoy the game and you don't have to be hunched over the PC to play it.
The Witcher 2 is also great with Xbox controller. Two World 2 as well.
I think you should include it, especially since the combat is TB and you don't need precision of mouse to frantically click around while your characters are engaged in Real-time combat ala Baldurs Gate, etc.
P.S. Why not develop it with Xbox controller in mind (like Witcher 2 was) and later you will have an option to release it on consoles.
