Best Game Engines of 2021

With respect to game development, choosing the correct game engine for creating a game can be quite frustrating and can make or break the entire game building experience. There are a lot of factors to consider.

  • The type of game the user is trying to make
  • Whether the game is three or two dimensional
  • The experience of the user
  • The engine’s or framework’s support and community
  • The resources available for the engine

Taking all these factors into consideration, it can be really challenging to make sure that they pick the right foundation to work from. This is even more important in today’s age when technology is continually evolving, which means that new engines and updates are coming out all the time with innovative features.

Therefore here is a list of the best game engines in 2021, along with the strengths and weaknesses associated with each engine to help with the process.

Unity

The Unity engine was developed in 2005 to become a staple of the indie game industry. With new major features and constant updates like Unity Reflect being added every year, the support for the engine is incredible. The engine is well-suited for both 2D as well as 3D games of all types, and is also a popular choice for AR and VR development, thanks to the wide range of companies and developers creating the best SDKs for the engine. Unity also has a sizable community beyond this, with an active Asset Store with free as well as pay-to-use assets at the user’s fingertips. Since it is such a robust engine and free for developers earning less than a hundred thousand dollars a month, it is simply a fantastic choice for beginners irrespective of what they want to make.
