Every time I release a game for the Gameling, I get a message saying that the game is not popular with the target audience. My latest Gameling game got 9.75 average reviews, and sold 190K units in the first two weeks, but the message still appears. It is an annoying message, and it often makes me lose confidence in releasing Gameling games, despite its popularity
Gameling is for a young audience, so make sure the Topic is aimed towards Young Audience. Also only Action really works on the Gameling.
So it’s not a bug 
Wait, what? Only Action works?
RPG works well on the Gameling. Try a Fantasy/RPG aimed at a Young audience and call it Pokemon.
Oh yeah forgot to mention that 
Thanks for replying. I tried a action game for the Gameling and it worked. Since then, I’ve been trying to create GS, PPS, grPhone and grPad games, and all of them are bringing the same message. Can you please clarify what are the best topics to use for these devices?
Brilliant thank you.
