1. It took 5 years not 8 and the reason GT5 took so long is because PD were using a new engine, GT6 won't take as long since the engine is already done.
2. How did the game flopped? where are the official sales for GT5 at? exactly stfu.
3. Whats wrong with adding more features to an already feature packed game?
GT5 looks better then real life, better resolution and better fps
