Project Statement

Overview

The purpose of this project is to create a virtual pet application for the Android client. The virtual pet game we are creating will be related to the Tamagotchi digital pet device that was originally released in the late 90s. After receiving much fame, newer generations of the device were created and marketed, packed with new features while still retaining the original concepts.

Customers

Our target customers are casual gamers with Android phones. Recently, the definition of a “casual gamer” has become a very broad term, especially with the introduction of Facebook games, most notably Farmville. As such, our target customer base can apply to all people who own an Android.

Goals

The primary objective of this project is to recreate a true replica of the classic Tamagotchi game device on the Android, with upgrades and features in order to benefit from the Android’s additional capabilities.

System Functions

Evident

The Tamagotchi Application should be able to take advantage of the Android’s GPS system in order to determine the current weather in the user’s location, and project that weather into the game’s environment.

The users will also be able to hold online battles with other users. Their battle levels will determine the chances of a user winning. There will also be a database that will hold all the statistics of the Tamagotch, including but not limited to, number of battles fought, number of victories, and age.

There will be an incorporated inventory system, with items that can be used to take care of a Tamagotchi, items like food and medicine. Additional items will be put in-game.

Hidden

None as of now

Frills

An Achievement System will inform the user of accomplishments made throughout the game (i.e played 10 battles, Tamagotchi survived 25 days, etc.). An additional notification system will notify the user through some media (pop-ups, email, etc.) on updates on their Tamagotchi (when its hungry, sick, etc.).

There will be minigames based around the Tamagotchi that the user can play and earn achievements.

System Attributes

Details/Constraints

During normal usage, the Tamagotchi pet will randomly walk around the map. Hunger levels will increase as the Tamagotchi remains active. It will also randomly poop on the screen.

We hope to achieve widespread usage of this application, so it will not be system intensive. All Android clients should be able to run this application.
