Why hasn’t there been a full Nintendo DS style Pokémon game for smartphones?
Nintendo might not release a full Nintendo DS-style Pokémon game on smartphones because they don't view mobile gaming as a core revenue stream, but rather as a means of attracting audiences to their main product: video game hardware and software They believe that mobile games should be tailored for the platform, which is why they made "Super Mario Run" instead of porting "Super Mario Bros."Another reason is that the core feature of Pokémon games would need to be reworked for mobile: connectivity While Game Freak worked around it for the Gen I and II 3DS Virtual Console games, it's unclear if something like that would be viable for phones Trading and battling are core aspects of Pokémon games, and without them, Nintendo and The Pokémon Company might not see it as worthwhileHowever, there are Pokémon-like mobile games available, such as:
This game focuses on battles with teams of three Pokémon facing off and includes famous faces from Pokémon lore
A port from the 3DS, this game has a Pokémon-style battle system and allows players to raise monsters by hatching eggs
