Ali hasn't boxed in 30 years. Exactly.
Molyneux has made a bunch of great games in the past (Populous, Dungeon Keeper, Theme Park, Syndicate), if he had retired after Dungeon Keeper the comparison could hold ground.
However he kept going and kept underdelivering: Black & White, Fable, Project Milo, Curiosity, Godus. None of these delivered what he promised.
That's akin to Ali not retiring and losing every subsequent match he fought.
Molyneux is tainting his own myth, actually as of now he probably made more average underdelivering and underwhelming games than actual great ones.
Heres a quote by him from
Tech Radar about the Kickstarter.
Some might call it "over promising", others might call it it "saying stuff you have no intention of delivering or no way of making happen in order to gain money", others might just call it "lying".
Some might call it fraud.
Oh Molyneux you poor soul! The rules are really harsh on kickstarter that's right, because you don't get to keep the money people donated to you, since there wasn't enough interest in your unbacked promises, so you overpromise shit just to get the money. Such a harsh world you live in.
