Ultima VII: The Black Gate
If you haven't played Ultima VII until now, then DON'T buy it unless you have tried Ultima I-VI. This is because present players like to play 3D style games like Revenant, Planescape: Torment or Diablo. You'll be disappointed with Ultima VII because it has a 2D graphics engine, but you can interact with virtually every item in the game.
Things such as move, take and eat are possible for anything that can be carried. Origin sells the Ultima VII: Complete Edition which includes Ultima VII: Black Gate with Forge of Virtue and Serpent Isle with Silver Seed add-on. In case you don't know, Ultima VII was released before 1996, so think how the game would be. To get a better idea, view the screen shots for Black Gate or Serpent Isle.

Basically, the game requires a slow system. If you try running it on a modest Pentium 4 3000 MHz system, the game will run mighty fast. This website has utilities you need to slow down the game, spoilers and a couple of other files.
