not all the time. In some of the early jrpgs, I think the random encounters can become a "zen like experience" after you've been playing for awhile like in some shooters you just get into killing the aliens and forget all else.
But if you have other stuff you need to think about doing theat are taking away from your full absorption in the game, then they can start to be a bother.
The worse thing about them is they can lead you to level up your characters too soon relative to where they are supposed to be in a rpg's storyline.
