I wont stop Blockland unless I'm distracting by life, as someone else explained; i.e. work, girlfriend, college, etc.
But I mean, if the engine changes, that would be good. But if it entirely changes the way you play Blockland and it's worse, I'm quitting most likely. But I will say that I'll never be too young to play this. But.. I wont be 40 years old and playing this. Badspot can do that, but he's cool like that. Anyway, yeah.
