User blog comment:Math34/The future of League of Legends/@comment-24946635-20150823192309

Well, the game of chess has been surviving for hundreds of years now without any significant changes to its gameplay. The question is about the user base's enthusiasm and the ability of people to find ways to innovate. League has a fairly slow and continuous rate of change. It gives people the chance to continue to innovate, so I don't see the game dying out.

I think the number of champions will eventually reach a limit. There are only so many champions you can stuff into the 5-6 possible lane positions. If they create a new map with different numbers of players or a different play style (no Nexus), then I expect the champion cap to expand.

There is the possibility that other MOBA games will compete with League and take away its player base, but I think that League is keeping up and developing.
