Baldur's Gate was quite possibly the best RPG ever made.

On modern computers, you may encounter a problem where seams show up beween the 40x40 grid of "tiles" that make up the screen. While this can be solved by disabling 3d entirely, the game runs smoother with it - so instead, use your driver control panel (ie, nvidia control panel) to disable antialiasing specificly for that application.

No more seams.
