Hello Farmer! Welcome to the lovely, beautiful town of Pelican Town! I understand that it may be some time until you come to terms with your grandfather's passing, but please let me know if there is anything that I or any one of Pelican Town's residents can do to assist you.
I have left behind this guide to assist you during your first year in the Valley so that you may grow accustomed to and explore everything this town and surrounding area has to offer.
This guide will give you a comprehensive idea for what to expect during your first year as well as give you suggestions for what you should do. From what crops to plant to what to do at each festival, this guide will have it all.
If at any point you believe that there is something missing or that you would like further information on a topic, I suggest you also utilize this guide along with the official Stardew Valley Wikipedia so that you may gain the best understanding of the game. If the Wikipedia still does not answer your questions, there will be a form that you may fill out in the "About" section where you may ask further questions.
That's all I have to say! Happy Farming, Farmer!
