I agree with you on most things but 11 in special. Uncharted 2 didn't have leaderboard when it came out and it was a lot better than since everyone was just playing for the fun. It did have personal stats on the website though but nobody seemed to care about them like they do about the ingame stats.
exactly, just a more realistic multiplayer,
I would add to the list not having three joels, and 4 ellies killing each other, it would kill the ambience, the charachters could be just like a custome survivor, with a great variaty of customization
