How Do I Create a Spiritual Game Successor?

An anonymous reader writes "I've recently been on a legacy video game binge, reliving the nostalgic days, when I realized that one of my favorite old games can be vastly improved with a few tweaks. This game is pretty much made for a controller, so I would love to get it done on Xbox Live, but doing it on the PC is just as viable. Unfortunately, I am pretty sure the game is not in the public domain yet. Based on previous stories covered here, some companies are all for community made successors while others choose to give them the crushing blow from the start. My question is: how far is too far when one is trying to make a spiritual successor? I do not intend to copy any materials, but it would be lovely if I could incorporate some game design ideas (very general level design, movement, and just one or two game features)."

Here's what I did...

If it is an individual who wrote the original game, ask them for permission. Both times I've asked, I've received permission.

If it is a faceless mega-corporation, avoid using images, music, or names from the original game, but unless they have a patent on the look-and-feel or game mechanics (never heard of the later), you can just code away.

For my platman (old Amiga game) remake for the GBA, you can get it on my web page. (www.greasybastard.com)

Also see freeciv, and any of the two-or-so decent Wing Commander Privateer remakes.
