I have to agree with Sean Murray, founder of Hello Games, when he says that "leaderboards are very dead to most people. We've all gotten used to the fact that we're not going to be at the top of leaderboards so they're not really alive to us anymore, I think. I don't care about them, and I think a lot of people don't. Unless you're number one, you don't care that much. When you're number 10,000 or whatever, that might be impressive, but really, it's not."
So the solution that Hello Games came up with is somewhat along the lines of what Trials Evolution did. Basically, you will see the ghost data of people playing the same level you are that brings sort of a simulated multiplayer experience into the single-player. You'll be seeing up to ten colored streaks with people's respective Gamertags as they race through the same level. You always see the person at the top of the leaderboard, plus your friends, and really anyone else playing, whether it's their past data or their live data as they're playing it, well, live.
Now being the top player means more as your ghost data will be in everyone's faces directly instead of just being displayed on some leaderboard that will barely be looked at.
