I also found the keyboard a fine choice for The Old Republic, but as usual, I encourage hardcore MMO players to check out keyboards with extra macro keys.
Batman: Arkham Knight tends to work better with a controller than with a keyboard, but if you don't want to dish out for an extra peripheral, this device is as good a choice as any gaming keyboard. The responsive keys helped me get the jump (literally) on my mech pilot opponents in Titanfall gathering and commanding my futuristic army in Legacy of the Void was equally simple. The keyboard performed admirably across the board.
