Ok so I've played Oblivion on the Xbox 360, and I really want to play again so I was thinking about buying it for the PC, specifically a laptop. First of all I was wondering if I can play without a mouse? I'd pick one up if need be but I'd rather not if possible. Secondly is it worth paying the $25 for the Shivering Isles, NoN, and the other smaller DLC's, or should I pay $20 not getting the smaller DLC's? Thanks for the input. Tom
