If you just do what is currently in the top charts or trending you have a high chance of failing!
Hit-Games are already on the market and many ad-campaigns are running. This means a lot of people have seen this concept. So you would already be behind the competition before you even start developing your game.
Your goals for ideation!
- Profit from market-trends without competing directly with similar ideas and demands. Your idea has to be different enough to feel new, create a market niche and make the competition irrelevant.
- Get an understanding of the current market situation. With this knowledge you can compare and rate your ideas with already existing ones.
