Like I said, I'll be waiting until BG2 enhanced edition.

The hand-drawn 2d art means BG2 is one of the least dated looking games on the GOG catalogue.

I'm not sure the EE is going to improve much. It might even offer a slight downgrade on the original art and music in some ways.

Up to you though. I'd recommend IWD instead if you want decent combat.

Planescape almost plays like an adventure game. It requires a lot of attention and patience to keep abreast of the plot. The setting is unique compared to your average fantasy game and the story asks you to think about more than how big a sword your guys are carrying.

Icewind Dale (series) throws a standard fantasy story at you, makes you roll up a spreadsheet of numbers and then whips their arses by exploiting every infinity engine pitfall and D&D rule it can. Scripted battle after scripted battle is the meat in this sandwich, where beating the random number generator through meticulous knowledge of the D&D ruleset is its own(ly) reward.

Baldur's Gate is a happy middle ground, and probably why its the unquestionable fan-favourite of the three. The story is a bit more personable than Icewind Dale, but still bog standard fantasy stuff. The unforgiving battles a little less frequent (but still there on occasion). Something for both Torment and Icewind fans.

Its hard to go wrong with Baldur's Gate. If you want something with a thought provoking story, try Planescape (my favourite). If you want something that's an unflinching challenge to your infinity engine/D&D skills then inflict yourself with Icewind Dale.
