I define “Neverending games” the ones that have almost unlimited replayability. A very good example are the Sid Meier’s ones 🙂
Games like Civilization can be played for months without problems (I know someone that still has the original Civilization and occasionally plays a match…!)
I won’t dare to say that Magic Stones will be replayable as Civilization (eh it would be too much) but I’m looking forward that direction.
The process should be simple: you go around the map and you gather artifacts and make experience, then you partecipate the tournament of the druids every year (have yet to decide how simulate a year). If you play well you get more experience (but no new items). While if you play badly (if you lose with less powerful opponents) you actually LOSE experience (and since the game gets saved automatically, you can’t cheat… well, in theory!).

That way I hope people won’t stop playing the game after some weeks…!
