Baldur's gate series Enhanced editions worth it?

Yes, I own both BG 1 & 2 Enchanced Editions on Steam.
The interface menus have been given a facelift; there are new party members, game modes, and NPC dialogues; and the game now runs in high-res & widescreen.

Excerpt from the above article:

"With the Enhanced Editions we set out to create the best possible version of Baldur's Gate you could find. We've made massive improvements in everything from true-type-font support for crystal clear text to repainting every pixel of the UI at over four times the resolution of the original game. We optimized game areas to load instantly, eliminating thirty-second-plus load times for areas. We brought in the original source-rendered area art for BGII, removing a lot of banding and artifacting.

We fixed a huge number of bugs in the original game, including inconsistencies such as trolls who did not die when struck by a fire-based attack. We added a true widescreen support mode which allowed the user to play the game at massive resolutions while keeping the clear fonts. In short, we've put a ton of work into the game and I encourage people to have a look back at the original to see how far we've come."

-- If you are still unconvinced, and do not want to buy the Enhanced Editions on Steam, then HERE you can find instructions on how to mod the GOG version of the game (they only sell the regular versions of BG 1 & 2), to nearly the quality of the Enhanced Editions.
