I am currently forced to game on a laptop, and was on verge of viewing life as empty of all meaning, until I remembered Baldur's Gate (and Good old Games). My question is as above: can you play Baldurs Gate without a mouse, and what impact does mouse-less gaming have on your game (if any)?
From memory, there was a legion of keyboard shortcuts, but the only way to interact with objects was by mousing over and clicking them; I am 90% sure there was no way to "tab" between interactive items, and, for better or worse, Baldur's Gate was way before the current age of context sensitive controls.
Even if there was, you'd have to have a way to move your party/characters and control orientation of the formations of your party... I know it's Baldur's Gate, but it's probably more trouble than it's worth :P
