The Smurfs: One Grand Adventure

The Smurfs: One Grand Adventure is an open-world strategy game released in 1999 for the PlayStation. It was a collaboration between Runecraft, who provided the assets and gameplay, and Cor-Son Games, who helped polish it. Infogrames published it, as they owned the license for the series. While it wasn't a major success, it has gained notoriety for its gameplay and how it's executed. A Game Boy Color port was planned, but scrapped due to the publisher wanting to focus on other Smurf GBC titles.

Gameplay
The game has you lead a pack of Smurfs to the mountains, where it's rumored that there's an abundance of food (actually a trap set by Gargamel). You pick five Smurfs to lead the group, and their success depends on who has the highest authority. If you make the wrong decisions, you could risk losing a Smurf and having it replaced by a different one.
