EarthBound/The Beginning

The first part of the game is mostly just for getting used to the controls. You start in your room.

Your House
You hear the boom, etc. Get out of bed and walk downstairs. Talk to your mom and she'll tell you to change out of your pajamas. You then start back in your room, fully dressed. Continue outside.

Up the path
Now just follow the path around to the top of the hill. Be sure to grab the bread roll from the present. At the top, you can see the meteor glowing, but the police set up a blockade so you can't get by. Pokey is bothering all the cops. Talk to everybody and then walk all the way back to your house. Your mom should be outside, and she'll tell you to go back to bed.

Your house again.
You'll wake up again. Go downstairs or talk to your sister. There'll be someone knocking on the door. Pokey will tell you he lost Pickey and ask for your help. Then talk to your mom again, and she'll make you change into regular clothes. When you get downstairs, talk to your sister for a Cookie. Also, stop in your sister's room for the Cracked Bat. This is your first weapon. Equip it. Then just talk to your dog and Pokey to make them join your party and head outside.

Up the path, Now with enemies!
This time, animals will attack you. Try not to face away from the enemy or it will get an extra attack. Make sure to fight and gain a level or two to get used to the battle system. If you need health, eat the Cookie or use Lifeup Alpha.

Keep going up the path and battling the animals. Once you get to the top of the hill, the blockade should be gone. Go up past the meteor. There, your dog runs away. Go and talk to Pickey who is sleeping near the meteor. Welcome him to your party and start to leave. A cutscene will be triggered which will reveal the main plotline.

Buzz Buzz
For whatever reason, a bee from the future comes out of the meteor and explains the story. He says that in 10 years, Gigas will take over and you can only prevent it by acting now. He will then join your party. Again, head back down the mountain. When you get to the end of the path, a Starman Junior will appear for your first boss battle. Don't sweat it though because you can't lose!

Pokey's House
Here, just walk in and watch the cutscene. Pokey and Pickey will get in trouble and then their mother kills Buzz-Buzz. Talk to him, and he'll say some last words and give you the Sound Stone. This is an important item, but it activates automatically, so don't worry about it. Now when you go outside, the night will turn to day, and you are ready to begin your adventure!

If you go back to your house again, you can get a picture from the camera man and heal or save. Your mom will always Heal you if you talk to her by making you your favorite food.

Now, you can go to the main part of town through the east path.
