Project Milo creator Peter Molyneux has admitted he finds it "insanely hard" to convince others of the validity of his new game ideas before they're realised.
The Lionhead boss told Eurogamer in an interview published elsewhere on the site that getting people to buy into his ideas is "a massive problem".
Molyneux has two games in the works: Xbox 360 and PC role-playing game Fable III, due out in October, and Kinect game Project Milo, which is currently without a release date.
Relationship sim Project Milo has endured a troubling time since it was unveiled at E3 2009.
Last week at the TEDGlobal Conference in Oxford Molyneux said Microsoft had no plans to release Milo & Kate, according to a BBC report.
A fortnight previous, Microsoft mouthpiece Aaron Greenberg said "right now it's not a game" before changing his mind, after which Molyneux waded in and said Greenberg's original comment was based on out-of-date information.
This week Greenberg told Eurogamer that there's still a chance that Project Milo will be released – but not this year.
"Where there's still a huge problem - a massive problem I have - not so much with Fable because Fable's a proven franchise now, but with this other thing we're working on, and anything new I come up with, it's getting people to see what you're trying to do, what you're trying to invent or create, before it's actually done," Molyneux told Eurogamer.
"That is insanely hard to do."
"The best analogy is if I had invented the bicycle. Let's say you've never seen a bicycle before, but you were funding me. I say, 'I've taken all your money and I've invented this thing. You sit on this saddle and you balance on two wheels and you go 16 miles an hour, and it's going to be the most universal mode of transport around the world'. You would look at me as if I was crazy.
"Even if you saw the bicycle, you'd still say, 'No way am I going to go on one of those.' It's not until you sit and ride the bicycle that you realise this idea is going to work. So often with big ideas, whether they're parts of a game, like in Fable III, or whether they're entire games, it's hard to get people to see the pictures in your head."
