Based on Maxis' The Sims franchise, MySims enables users to personalize their in-game character, build relationships with their neighbors, and design homes, shops, restaurants, and more. The PC edition will feature 'shared online game spaces' in which up to eight users can populate the same online neighborhood. Players can chat, play games, construct buildings together, and share their creations with each other. In addition, players can send their creations to each other through email or instant messages.

Electronic Arts also plans to release a follow-up for the spin-off series this fall titled MySims Kingdom. Planned as a Wii and Nintendo DS exclusive, the sequel will challenge users to revitalize the fantasy kingdom of King Roland. Said The Sims Label studio head Rob Humble: 'MySims, made for the PC, opens up the world of MySims for you to explore, play and share with up to seven other friends that are online with you. For the first time, you can express the creativity of MySims with others in a collaborative way, as you create and live in a shared town with your friends online.' He continued: 'With MySims, made for the PC, it's a whole new world of interaction with personalized creations, buildings and towns to share, along with furniture and other tailored creations that you and your friends can trade. Players who enjoyed MySims on the Wii and Nintendo DS will view this as a great way to connect with friends in an online PC game and those new to MySims will find this a fresh and exciting game
