I was shortly working with similar guy, although from the day one it was free/hobby project. He as a leader couldn't keep focus, he was talking about mountains 200 miles north somewhere at 5h mark in game. Then at one point whenever he asked if I can do feature x, feature y, I said: let's work on first 5 minutes of game play. Ok ok. When he came up with another ideas I said let's work on first 30s of gameplay. Then whenever he get any more ideas I asked: "is this in first 5 minutes of gameplay?". It wasn't and the whole project went nowhere. I still have /r/inat I'm my RSS reader but mostly only for daily "I want to make MMORPG" posts.
