13 Legendary Free Game Engines for Beginners & Professionals

Free Game Engines for Beginners & Professionals

What is the best game engine? Why should you use a game engine in the first place?

Gaming has seen a total revolution – from independent (indie) games to Triple-A (AAA) games. But there has been an exponential rise in the popularity of indie games in the last couple of decades.

What is an indie game? It is an independently created and published game without the backing of a big publisher. If you are an individual or a team of game developers sans an extravagant budget, you will be developing indie games.

So how does a game engine come into the picture for an indie game developer? A game engine helps solve some problems that may arise in the development of any game. It is a software framework or environment that pre-designs physics, user input, rendering, lighting, and other aspects.

Given the budget constraint for indie game developers, we should only be concerned about free game engines.

There are many free game engines available today. And choosing the best game engine can be challenging, especially for beginners who have limited game development experience.

So, here is a list of the best free game engines for professionals and beginners. Make sure you stick around till the end to get some valuable insight about how to select a game engine.

Guidelines for Game Developers

Choosing the right game engine is crucial to ensure that your game development endeavors do not go in vain. There are many factors to consider when selecting the optimal game engine. These guidelines will help you pick the perfect option.

Features of a Game Engine

You need to know what features you need for the game you wish to develop. The majority of game engines offer four types of functions:

  • Coding – You may come across a game engine that has its scripting language, making it extremely easy for beginners to learn to code. On the contrary, there are game engines that rely on established scripting languages that you can master to gain total control over the game.
  • Drag and drop – One of the features that require zero coding knowledge is drag and drop. You can choose properties or events from a comprehensive list and drag and drop them to create them.
  • Full game templates – A full game template is a significant blessing for beginners. You get a ready-made game where you may change minor details. You can import your artwork or move some sliders to alter essential elements.
  • Visual Scripting – It is the best feature for beginners who want to understand how the code works but do not know how to code. You won’t have to type codes; instead, you can choose various functions that replicate conventional code. It is more effective than drag and drop but can take a while to learn and master.

Other Factors

There are some other factors that you should consider before choosing a game engine.

  • Game Genre – If you are developing genre-specific games, you should choose an engine for that specific genre. You may use the Adventure Game Studio for creating adventure games or the RPG Maker for creating role-playing games.
  • Perspective – You can choose either a 2D or 3D perspective for your games. Most of the new game engines support both 2D and 3D. 3D game engines are relatively complicated and involve a steep learning curve.
  • Computer – Are you using a Mac or a PC? There are a few engines that do not support both systems. Your computer specifications have to be good enough to run more powerful game engines.
  • Art Skills – You get in-built visual editors with some game engines, enabling you to create art – terrain maps or pixel art. You can choose to import backgrounds and characters from other programs.
  • Target Platform – Every game engine is not equipped to develop games for all platforms. Where do you want your game to be available – web, Android, iOS, PC, Mac, or VR? Choose a game engine compatible with your target platform.

Game Genres

Selection of a game engine depends much on the genre of the game you wish to develop. There are four game genres:

  • Simple 2D Games – It is the most straightforward game genre, but you will still have to invest some time to get used to the game engine. You can use drag and drop engines to develop 2D arcade games, puzzles, text adventures, and racing games.
  • Simple 3D Games – Developing 3D games is more complicated than 2D. 3D game engines are sophisticated and require considerable time and effort on your part to learn and master. You can develop survival games, adventure games, and first-person shooting games.
  • Complex 2D Games – Complex 2D games rely on AI, physics, multiple features, or multiplayer. You can create adventure games, fighting games, tower defense, and role-playing games using sophisticated 2D engines.
  • Complex 3D Games – Complex 3D games are meant for professionals and experts. Beginners will likely find it next to impossible to develop one of these games. It includes vehicle simulation, real-time strategy, sports, MMO, MOBA, VR, life simulation, and war games.

Final Words

Beginners will face a steeper learning curve, irrespective of which game engine they use. We have shortlisted 13 of the most user-friendly and productive game engines, which will surely be capable of developing your dream game.

Picking one of the 13 recommended engines depends on your requirements, but we hope our guidelines and tips help you make that choice.
