The important part to focus on here is "small". Any idea you have, shrink it. Make it 10x smaller. Create whatever that is. It's kind of the problem with games, they consist of so many fields it's easy to think you have a "small" idea only for that idea to actually be substantial. Then, reasonably, when you want to nail the details it becomes a gigantic mountain. To me this isn't perfectionism, everyone wants to nail details, but when the scope is too large it's difficult for that to happen - hell it's difficult for that to happen on teams of tens of thousands operating as cogs dedicated to their tiny section of work! Any one of your bullet points could have been the "small game" to demonstrate how large you're still operating.
