Essentially the Atelier games are RPGs, only your protagonist is usually a shop owner that specializes in creating items and equipment and typically the goal in an Atelier game is rather small scale - keep your store in the black, earn money to pay off a debt, etc. They also usually have a time mechanic - creating items and travelling takes time and most goals you're given have a time limit.
Also in most Atelier games typically only your alchemist characters, which will be your protagonist and maybe some others, can use the items - all other party members must rely on their equipment and skills.

I played Atelier Annie a long time ago on a whim after seeing it on new releases, and I thought it was definitely enjoyable for RPG fans who want something different. I never managed to finish it due to still not fully understanding how the game is supposed to want you to play it, but it was very enjoyable nonetheless.
don't get these games if there all like atlier merumeru. that game was terrible they give a three year time limit doing ANYTHING takes at least a day not to mention taking several days to make materials required pass a quest,and unlike majora's mask you CANNOT reset your timelimit.
So since you lack time management skills its a terrible game? I got ya good to know you can't be counted on as a grown up now...maybe ever.
