Ecco Jr.

Released after the two main Ecco games, this title is geared towards younger children with simplified gameplay, lacking the difficulty of the other Ecco games.

The game also contains a number of educational facts about dolphins.

Set in the same underwater world, players choose one of the three characters to solve a series of challenges.

These all involve harmless exploration and solving small puzzles with no foes or violent gameplay.

The characters need to use their abilities to locate animals, herd seahorses, retrieve a sea lion's lost ball, swim through rings and locate glyphs.

After completing the main tasks, a large glyph needs to be located to end the level.

The characters can be switched at any time during gameplay, but they all have the same abilities.

One button is used to send out a sonar pulse to locate items while another boosts the animal.

Most levels take less than a minute to complete and there are eighteen levels in total.

Ecco Jr. for Sega Genesis is currently worth €29.24 loose, €445.49 complete in box, and €1113.74 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Ecco Jr. 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 Ecco Jr., loose is €29.24 and CIB is €445.49 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Ecco Jr. is currently worth €29.24 loose, versus €24.28 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
