Speak to any developer for long enough and they'll all end up using the same stock phrase: making games is really hard. And they're right, of course. Hundreds of staff working on dozens of interconnecting systems while publishers yell deadlines, point at budget spreadsheets and say things like 'we love it, but can we have more flying tanks?'. It's no wonder that, from time to time, the whole thing spins wildly out of control and a game emerges from development limbo looking very different from the one that fell in.
Well, here are nine games that changed massively during construction. Some were last minute changes in direction, others lost key licenses or swapped publishers. What they all prove is that while making games is hard, retaining that glorious initial vision is, well, more-or-less impossible.
