Oh I didn't mean this online gacha bs. Sorry for not making that clear. I meant if he wanted to, he could make a game, for example like xcom 2 but with girls(like girls frontline 2 but offline or like codename bakery but in 3d). Making a turn based strategy game is easier than making an action game. With an action game there are a lot of moving parts all interacting with everything around them at the same time. Enemies move, you move, skills you might have, skills enemies might have, environmental interactions... All in real time. It is hard. But a turn based strategy game that still plays like in that "joke" gif he posted is not that hard to do, even for someone incompetent.
