Pokémon Black and White/Nuvema Town

Nuvema Town
The game begins with a short cutscene. It shows Professor Juniper leaving her lab and traveling to the player's house. She will leave the house after a few seconds. The main game will then begin. You and your friend, Cheren are waiting in your room for your other friend, Bianca to show up. When she finally arrives, the three of you will open the box on your desk. Inside the box are three Poké Balls. These Poké Balls contain the Grass-Type Snivy, the Fire-Type Tepig and the Water-Type Oshawott. Tap the Poké Ball that contains the Starter you want. You will then be asked to confirm your selection. Tap yes to receive your Starter. It doesn't really matter which Starter you choose, as none of the Starters have an advantage over the types of the first two Gyms. Once you have made your decision, Bianca will choose the Starter with a weakness to yours, leaving Cheren with the Starter that has an advantage over yours. Bianca will then challenge you to a battle.

After the battle, your room will be a complete mess. Cheren then heals Bianca's Pokémon and then your own. After he has healed your Pokémon, Bianca suggests you and Cheren have a battle. You both accept to battle and you have your first battle with Cheren.

If you lose to Cheren, he will gloat about his victory before leaving the room. If you win, however, he will leave the room, upset that he lost. Either way, follow him and Bianca downstairs.

You will find Cheren and Bianca apologizing to your mom for the mess your room is now in. After a bit more dialogue, they will leave. Your mom will then speak to you and give you an Xtransceiver (this is actually called the "cross-transceiver", don't let the "X" confuse you). Leave your house and you'll find yourself in Nuvema Town. You'll see Bianca walk south, scaring away a flock of Pidove in the process (Woobat if you're playing during the night). Follow her down the road and enter the house on the left. Inside, you'll find Bianca's dad shouting at her because he doesn't want his daughter to go on a journey. Bianca will then leave the house and head over to Prof. Juniper's Lab. Leave Bianca's house and head to the northwest corner of the town, where you'll meet up with Bianca and Cheren. The three of you will enter Prof. Juniper's lab. After a chunk of dialogue, Prof. Juniper will ask if you want to nickname your Pokémon. Nickname your Starter if you want. Juniper will then ask you to complete the Pokédex for her. Select 'yes' and you will obtain a Pokédex. Now, leave the lab and you will come face-to-face with your mom. Bianca and Cheren exit the lab also and stand with you. Your mom gives each of you a Town Map, which brings up a detailed map of the Unova region when activated.

Now that all that's done, head northeast onto Route 1!
