If one person were to give up on an idea, it would ruin the entire game. If one person decides to change the design of one character, it ruins everyone else's work, if one person abandons or gives up on the entire game, a major hitch will occur. Each person contributed to the team's success. All parts of a project need different people to make it work. This is also why you make a game that everyone can agree on. If a person doesn't like the project they're working on, less effort is put into it. From my interview with Martin Sahlin, who worked with another person, I could understand the truth behind this. Martin Sahlin believed that "there's something really special about working on a game of your own." Most likely, the main reason he didn't like his job at Raster Media, a gaming company, was due to his lack of input. He wanted to make it happen for his own desires and not for a company. He was true in his statement, but I think the main reason he didn't like making games with Raster Media was because he wasn't part of a great team. Working with multiple people allows you to really clear your head and decrease the workload you might have on a game. It can also allow you to expand your ideas even further and create bigger games that more people can make
