Second Life Baseball, also known as SLB, is a baseball career simulation game developed by 이번생스튜디오. It invites players to create a personal baseball journey, beginning as a high school senior and continuing through the professional draft, seasons, contracts, and retirement. Rather than focusing on a single match, the game follows a player’s growth and career over time.

Players can start a new baseball life, pursue one-to-one career matches, and visit a club clubhouse. Competitive features include team battles, live rankings, server-first achievements, and rookie award candidates. The site also offers mini-games and a shop with options to expand player and team slots. Community features provide spaces for baseball discussions, player stories, user posts, and bug reports or suggestions. Players can also support the costs of operating the server.

The website includes a game guide, FAQ, introduction, and notices to help users learn about the experience. Second Life Baseball is classified for all ages in Korea, according to the information provided on its site.
