Community projects tend to fail more often than indie projects. Too many people with too different opinions how to do things kill each project pretty quick. I doubt there would be even kind of a community Pac Man. Even that simple game would fail.
One remember Hans "The Definition Of Vaporware" Wittman?
Even with his ingenious team of the best of the best they not even were able to create a web page. Remember? 2016 was the year Atlantic Warfare should be released.
Every team member of such a community project has different views how such a project shall be. Usually community projects start to become way too ambitious, want to create the next Uber game with heaps of features. One wants to create a multiplayer game, the other prefers single player, one more action, the other more simulation.
Better is to have a small team, not more than 5 people.
