I'm working on a Yume Nikki fan game at the moment. It's slow going as I fumble uselessly around RPG Maker, arguably one of the simpler game building software available, but every time the game manages not to crash it's an achievement in my eyes.
Of course when working on anything you get ideas of what sort of direction to go in, events to add and the like, but sometimes you also get an idea which doesn't fit into the context of it at all but seems like a shame to discard. After downloading a couple of different fan games, I wondered if there were any attempts to simulate Yume 2kki by western developers and the answer seems to be...kind of?
