First Sonic Boom on 3DS, a slower 2.5D platformer compared to classic Sonic. Simple puzzles and readable team exploration. Decent presentation, pace too slow for many fans.

Collector interest

Japanese version of Sonic Boom Shattered Crystal, distributed under the Japan-specific Sonic Toon Island Adventure banner. The first entry of the Sonic Toon branch, it shares the Boom series' weak commercial standing while benefiting from a reduced Japanese run. Its interest rests on the local branding and the relative rarity that follows, prized by completionist Sega collectors.
