Unless this is indeed to port the game over to tablets (I shudder at the foolishness of it being ported to phones... because no matter how advanced phone screens are, teeny tiny sprites in the palm of my hand only serves to infuriate me with their teeny-ness), then I'm not interested in paying for remakes of things I can still buy (*cough*or download*cough*) for virtually little expense and a shiny new coat isn't really enough of a reason for me to pay a premium price for an old used car, to attempt an analogy.
Unless they add new quests, new characters, revamp the combat system and dialogue options to deepen the experience beyond "pre-battle conversation and posturing", then I'm happy with my classic collections on disc.
Someone let me know when someone gets around to making another planescape or Septerra Core 2.
