I also prefer a pretty spartan life. (My kids, on the other hand...) But I do get nostalgic for the old days of PC gaming. Opening that Ultima VII box, studying the Compendium and the cloth map of Britannia...
If this came with a sweet star chart or a solid Settler's Reference Manual, etc. I'd be interested. If it's just some plastic model...pass.
From a digital perspective, a good soundtrack is always nice. A phone app that actually did something in-game would be pretty cool. Imagine you could play Fallout: NV but your Pip-Boy could be on your phone while you played. Or in a Star Trek-like setting, it would be like your communicator and/or Tricorder.
