There's safety in a known model, of course, but you'll have to do a lot of legwork in promoting the game in order to sell copies.
The good news is, any game you make with GDevelop is yours to distribute as you wish! So, you have the right to sell your game wherever you want, however you want, for however much you'd like, without ever giving GDevelop a single penny. Neat, huh?
In the world of mobile gaming, in-app purchases reign supreme. In very basic terms, in this model you get the base game for free, say, from the Google Play Store or iOS App Store. You can play for free, too. But in-game items which might make it easier or more enjoyable for you to play the game are locked behind a paywall: if you want them, you have to pay with real money.
The trend at the moment is to exclude upgrades which affect the balancing of the game, and focus on aesthetic items or timers instead. Nobody wants to feel like they're playing a game against people who have just paid to win. So, if you're going for an in-app purchase model, be sure to focus on items that do not affect the balancing of your game. Incorporate this mechanic as early in the game development process as possible.
GDevelop has a community extension which makes in-app purchases possible. It still in its development stage, but you can already try it out in your own games.
You can even make games on the go! GDevelop has Android and iOS apps for iPhone and iPad. So you never have to stop making your dream game a reality.
This is another staple of mobile gaming, and it consists of displaying advertisments to the player in key UI locations or moments in the game. Every time a player watches an ad, you get paid.
The biggest hurdle with this model is that you need a lot of users to make any significant money from ads. But that shouldn't stop you from trying, because it's one of the most flexible revenue models and it has a long tail. You can just leave it on and wait for people to watch enough videos on enough of your games to make a difference.
GDevelop can incorporate AdMob ads into your games very easily. With this, you can display ads and get paid every time someone watches an ad on your game. You can follow the instructions to add AdMob to your GDevelop game by clicking here.
These aren't the only revenue options out there, but they are the most common. You can also make a game on-demand, from a client. Licensed video games are a great way of getting into the industry and making a name for yourself. And they pay you up front in a lot of cases!
You can also sell game templates and other assets on digital storefronts. But we'll touch more on that later.
For now, just know that if you're thinking about how to make money making games, GDevelop has you covered regardless of which revenue model you choose.
