And you very likely would still get that after this remake releases. The Black Isle games have a devoted following, and an original 4 disc big box release, mint and complete is what the collectors are after, not the two disc "combo pack" release and not a "greatest hits" type of release that this DVD is.
This reissue is really nice for those who don't have the original or can't run it for whatever reason, and hopefully will have some updates to the code. That said, I have run the original on XP and Vista with no issues and with the hi-res patch the game looks much better.
It is a unique and quirky game, with what many consider to be the best written storyline and some of the deepest character development in gaming. It is not for those who don't like to read, as there is a LOT of reading, and you miss what makes Planescape different if you just click through it blindly. The game feels like a lot of "developer love" went into creating it, no doubt of that.
