Baldur’s Gate 2 holds a place in my heart as my favorite game. It had a lot going for it, and that little company Bioware that made it you may have heard of before. However, I think a lot of the success and nostalgia come from the excellent voice acting, this being one of the earlier games to really do this well.
Meaning that the driving force behind it, the best voice acting, the plot, all comes back to the villain, Jon Irenicus. He is a rare sort of character in a fantasy world: an evil elf. Doesn’t happen very often; Elves are usually various shades of good, or else maybe there are Dark Elves who are evil. But Jon Irenicus gets to put all the years of experience learning how to be a mage into action as an evil one, and it is scary.
