Which Sega console was Lego Fun to Build released for?

Lego Fun to Build was released for the Sega Pico.

The game arrived in Japan in 1995 and is generally recognized as the first commercially released Lego video game. Sega developed and published it as an educational title aimed at young children, rather than as a traditional action or construction game.

The Sega Pico was an unusual children’s console whose software used illustrated cartridges resembling book pages. Players used a stylus and the console’s touch-sensitive drawing surface to interact with activities. Lego Fun to Build combined building puzzles with minigames and a free-form drawing or creation mode.

Its themes reflected Lego’s mid-1990s product lines, including Town, Aquazone, Castle, and Space. A common mistake is to name Lego Island, released in 1997, as the first Lego game; Lego Island was the first Lego video game released outside Japan, not the first overall.
