It all sounds pretty exciting, Erik! I would suggest you to work on the second idea. I don't know, it sounds more original than the other two, you really should give it a try. Also, your plans for Derelict sound awesome, but I would suggest you then to use a different name for it. Maybe using a subtitle. I say that because it would attract more attention to the game, it wouldn't sound as if you just updated it. Also, it would make it easier to add it to MobyGames. =)
 

And you can count on me in whichever of your projects. Cheers!
