DT:Leviathan is best enjoyed if you already have friends playing. It's a game that offers little to the solo player, despite the single-player campaign. With pals, it's an entirely different, much more entertaining experience. If you do have a tablet, then I recommend picking it up for that rather than PC, purely because of the much lower price. All versions are completely identical, so you won't be missing out unless you desperately want to play it on a larger screen.
