I guess if it would die, i'd go play other games some more, but it would never be quite the same. The thing that makes jj2 so special to me is that so few people play it, which makes the community like one of those tiny villages where everyone knows everyone. This creates a very pleasant atmosphere you'd never find in those millions-of-players-games like Warcraft or Counterstrike. Other than that, i like the cartoon style jj2 uses. Now that all game companies seem to be bent on making their games as realistic as possible, i wouldn't like gaming very much if i couldn't get back to an imaginary, completely flat 2D game every once in a while. JJ2 is nearly the only game that 1) fits this description and 2) can be played online with other people. So, my answer to your poll would be: no, it'll never get boring. If it does, it's only temporary.
