What Kind of Game Applications are you Planning to Develop?

There are different types of games. You need to decide on what your type is and based on that you can proceed with mobile game development. Here we have executed 4 key types of games to help you decide:

1. Casual Games

Casual users are prone to spend irregular time periods actively engaged in the game. These kinds of games can be created in any genre, its market is comparatively larger.

Generally, these games are created with less complex rules and a simple tap-and-swipe interface, Subway Surfers and Cadycrush are prime examples of the same.

The audience of casual games is generally bigger, and the number of casual game downloads is pretty much higher than that of other kinds of games. 

2. Mid-core games

Mid-core games are a tad bit more complex than casual games, from the perspective of production as well as character development and overall gameplay. In such kinds of games, users have to put in more effort and dedication into the game.

As game development companies are generating a good amount of revenue from mid-core gaming applications, we can expect it to continue being one of the trends of game apps

3. Hard-core games

Hardcore games are for gamers who don’t consider games just as their hobby, they are serious gamers. Think of games like God of War Ragnarok, Loot River, Stray, Suicide Squad: Kill the Justice League, and many others, they are typical hardcore games.

The audience of this kind of game category is generally youth and they spend incessantly longer periods of time playing games. 

Since such games take more than the usual period of time spent to become a master of it, thus these games tend to have generally higher user engagement.

4. AAA games

AAA are big-budget games and it requires a dedicated full-time team to work on it and produce such games. Similar hard-core games, they too call for ample time and commitment to get the hang of it.

Up until now, AAA games have primarily been launched for PC or console gaming. As smartphones and data streaming are still not well-suited for games categories like AAA, we will see bigger game titles released for mobile gaming super soon.

So, these were the top 4 categories of games. Games are generally divided into these 4 categories. Let’s move forward to learn about segments that will guide you to create a game from scratch.

2. Story Matters

We, humans, are prone to look for stories everywhere we go. As we are creating games for humans, then stories should be the prime element of your game.

They will surely think of switching to a different gaming activity as swiping left and right is not something that will make them stick to playing it for hours.

A mainstream GDD includes information about the target audience, game genre, game world, gameplay mechanics, level design, character design, user interface, and marketing strategy. It may also include technical details, such as programming language, software requirements, and hardware specifications. 

The purpose of a GDD is to communicate the vision and goals of the game to the development team and stakeholders, ensuring everyone is on the same page and working towards a common goal.

It serves as a framework for the game’s interface or level layout, showing the placement of various elements, such as buttons, menus, text boxes, and interactive elements, and the relationship between them. 

Game wireframes are useful for identifying potential problems with the game’s design and allowing for changes to be made early in the development process. They are also helpful for communicating the design vision to the development team, stakeholders, and other members of the development process.
