I am completely addicted to Atelier Meruru. It's probably been almost ten years since I was this addicted to a game, to the point where I have been neglecting eating and sleeping to get more hours in. In all honesty I think I liked the story and characters in Totori better (Meruru lacks a driving purpose), but the gameplay has been refined to a whole new level in Meruru. Having the new third tier of development really helps, so now you have to split your time between crafting, adventuring, and developing. But they all complement each other perfectly and the feedback is pretty immediate so it leads to a constant feeling of just wanting to play a little more. Combat--which has never really been a strong point in the Arland trilogy--has also been subtlely improved and it's a lot of fun. Rather than just being something you have to do it makes me actually look forward to crafting the perfect gear and items so I can take them into combat.
Yeah, this game is friggin good. What a way to end the trilogy.
