If on sale for around $10 or less, not a totally bad game. If all you want to do is collect, build and paint gunpla digitally, it's good for that, and a much better deal than the endless grind and gambling lottery experience of the mobile game.
Graphics are much better in this version too. Story's not great, gameplay sucks, but if you turn off container auto-targeting and up the camera speed, it's playable, especially with a controller. At full price? Not worth it though.
