#3 Too Human
Too Human is estimated to have cost anywhere from $60,000,000 to $100,000,000 in development, which is quite a bit of money. However, we have to keep in mind that this game was in development for over ten years where it was originally set to release on the PlayStation before it finally found a home on the Xbox 360. Like Shenmue, Too Human was supposed to be a series of video games but told a story around Norse mythology. However, the game was found to be more mediocre with frustrating gameplay which left the game title to only move 700,000 units.
