This isn't a game. This is an early beta that's embarrassingly incomplete. Even if you can get it to work on your computer (no guarantee), the game itself is lacking in pretty much every aspect. Shame on the executives who pushed this out- it should have stayed in development for at least another year, possibly longer.
Planescape: Torment was one of the greatest CRPGs ever made. Naturally, I was quite excited when I heard about an enhanced edition release, given what Beamdog did with Baldur's Gate and Icewind Dale in their enhanced editions. I was looking forward to the possibility of new areas, quests, spells, and equipment being added to the game. What I got was a changed party interface and a few new options like the ability to auto-loot all ground piles. Compared to what Baldur's Gate got, this is really not an impressive showing. It's an improvement over the original, sure, but if like me you already have the original in you GoG library it isn't enough of one.
