In a multiplayer free for all death match situation, what is a good "leveling up" system? The obvious problem is that high level players can dominate the game, while level players face a long grind before they can actually compete with the old-timers.
The "obvious" solution is to make leveling only work in the match and not carry over to the next match. Also, one can make it similar to First Person Shooters: players go around the map collecting power ups, armor and weapons. But when they die, they go back to square one and respawn with nothing.
Unfortunately, I don't really know much about this topic beyond these few points. I will be so grateful if anyone has any good input/insight about this or has links to good articles talking about the design of these systems.
