Brain Age for Nintendo DS is currently worth €7.88 loose, €6.12 complete in box, and €9.84 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Brain Age has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Brain Age, loose is €7.88 and CIB is €6.12 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.
