A CORNER SHOP POST YAAAAY
ALL the nostalgia.
Okay, so, I'm assuming you already know that they are basically a collection of minigames - not much of a "story" involved. You run shops with your Tama partner and you can expand them. Yup. The games also quite simple - I was around 11 or 12 when the first one came out (I think?) and could tell that the game was targeted to a younger audience than me! But I enjoyed childrens' games and still do to this day so I had a lot of fun with them. The best advice I can give is don't try to expand just one shop all in one go, as you'll get tired of the repetition and get bored of the game
Corner Shop 3 is my favourite, as they added quite a few cute features, and a refreshing selection of shops - the gardening shop and piano school were really fun. In Corner Shop 1 and 2, you choose either Mametchi, Memetchi, or Kuchipatchi as your business partner and run the shops with them - but in Corner Shop 3 they added Violetchi / Furawatchi (whichever you prefer... :furawatchi: ), and you have the option to switch Tama partners anytime. They also added a cute little "journaling" feature where you can scribble down your innermost thoughts (though those thoughts have to be confined to the length of a tweet or so
). There is also a park that you can decorate and grow flowers in - your shop customers will visit and you can see what they have to say. You can also create unflattering Tamagotchi avatars of your friends and they can come visit you in the park too!
Also, they released a couple other Corner Shop games for DS in Japan that we didn't get here, that you can emulate if you're interested. I think even with little knowledge of Japanese they would still be fun.
