I seriously entertained the idea of making a mobile game for a short while. In this region, we have rows of these nice colonial-era shophouses along some older streets. Efforts have been made to preserve them as historical buildings and today they house all sorts of businesses, from hotels and hipster cafes to cycling gyms.
I thought I'd be able to get some government funding if I wanted to make a casual semi-educational isometric game about managing these shophouses - you'd rent them out as residential units, run businesses out of them, buy adjacent units and upkeep them so they pass inspections by the authorities. Residential units will be the easiest money-makers at first but, mirroring what actually happened, they eventually become less and less appealing - until much later when you can design affluent or luxury residences. And having a good selection of businesses along the street will also attract higher-paying residents.
But, not knowing how to code and needing an artist to make appealing graphics, I figured I'd need to spend more money than I could get on good talent for those. And then, even if people actually liked the game, I could be buried by copycats with much bigger budgets.
Yeah, making games today seems really hard.
