The Great Battle Pocket

The player starts at rank 50, and the goal is to reach the top ranking by defeating higher-ranked opponents.

Gameplay in the battles consists of selecting three unit cards from a pool of six and placing them on a three-by-three grid; placement affects a unit's attack range and abilities.

Players take turns commanding their units to either attack, defend, or use an item, and the winner is the player who either defeats all their opponent's units or has the most units remaining after 20 turns.

There are several different types of battles to participate in.

Many NPCs can be challenged to earn money, items, or additional unit cards, but ranking up requires participating in tournaments.

Many tournaments are only available at certain times, determined by a real-time clock in the game.

The player's rank will also slowly decrease each day when the game is switched off.

The unit cards feature heroes and villains from the Gundam , Kamen Rider , and Ultraman franchises.

There are 150 total unit cards in the game, with each franchise represented by 50 different cards in two different categories each.

The Great Battle Pocket for Game Boy Color is currently worth €34.19 loose, €24.28 complete in box, and €41.08 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

The Great Battle Pocket 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 The Great Battle Pocket, loose is €34.19 and CIB is €24.28 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.
