Many games with good design do this. Not just MMOs, as people suggest below, but practically any game that involves "getting better" over time. This is a really prevalent in RPGs with xp curves, but more generally negative feedback loops for people who are "ahead" and positive feedback for those who are "behind" is an incredibly common game design tool used in any game that wants to avoid the snowball effect where people who are winning will be able to win more and people who are losing are more likely to lose. This can be found in games as varied from Twilight Imperium to Mario Kart. Conversely, negative feedback loops for people who are losing and positive feedback loops for people who are winning can be found in all sorts of outdated, terrible game design like Risk and Monopoly.
