@LukeAlmighty @Chazcon Yeah, you're forgetting about pokemon and the many JRPGs on Game Boy, so yeah, RPGs can be done on an handhelds
It's just that mobile RPGs are usually poor "watch stat grows" simulator with even less of a story and gameplay than modern "half-assed" low budget JRPGs with menu world map like the Neptunia series. Here usually, the whole game is menus
The mobile RPG story mode is usually a completely unchallenging cinch, making it completely pointless to play at all, while the weekly events usually requires bullshit new pull of the week due to elements and such requirement to even get the super good event prizes
They also usually have abysmal pull rates, because the pulls are also mixed with equipable items that you're always disappointed to pull. Also you'll need multiple pulls of the same character to fully max it out, bullshit
In the end, the game ends up you putting it as auto play to do whatever daily task and doing the PvP just because you have to, which you usually fail hard against whales or manages to win in the quasi rock/paper/scissor mechanism, you just got lucky
I heavily disrecommend, if you gotta play a mobile game, play something that requires skills at the very least, like a rhythm game
