Which earlier building game helped Omega Force prepare for Pokémon Pokopia’s sandbox design?

Dragon Quest Builders 2 helped Omega Force prepare for Pokémon Pokopia’s sandbox design.

Game Freak and Omega Force were paired partly because Omega Force had experience with sandbox-style games. The development history specifically identifies Dragon Quest Builders 2 as one of the similar titles the Koei Tecmo studio had worked on before Pokopia.

The connection is about development experience, not shared ownership or story continuity. Dragon Quest Builders 2 belongs to the Dragon Quest series, whereas Pokopia is a Pokémon spin-off. Both games use construction and environmental design, but Pokopia adds Pokémon-specific systems such as learning moves from fellow Pokémon, attracting creatures through habitats, cultivating crops, and restoring a desolate setting.
