Its a good game, but there is always room for improvement. The battle concept should be expanded. Instead of just battling at gyms, players should be able to battle wild Pokémon, especially if youve already caught it. Pokémon can be rewarded with candy or CPs after completing a battle. Training against wild Pokémon was a major component of the original games, so making it available in Pokémon Go would definitely attract more of the core players.
