Well as a gamer in his 40's I'd have to say that I definitely find this to be plenty fun and right up my alley, tedium and all (and yes, I do think some things get tedious but that's the nature of a grind). Then again, I used to enjoy the grind back in Ye Olde Ancient Times of Vanilla WoW.

The easier the grind, the more shallow the victories. The easier the mats scavenge, the more shallow the success. The harder the game and the more time one must invest into its mastery, the more satisfying the experience is. Any MMORPG that has deviated from the above has fallen flat on its face.

I think it's less about your age and more about your play style OP. And that's fine. You play what you like. We'll play what we like.
