Unreal 4 VS Unity

Over the last decade Unity has become the game engine of choose for a good chuck of game developer out there. This is due to many factors, the main factor being that it was designed as a product first. Whereas a number of other engines where brought into existence to make a game. In my opinion this is the key difference between the two engines.

Unreal was originally developed to facilitate the creation of one the most beloved FPS of all time “Unreal Tournament”. Unreal Tournament was designed to be a fast paced shooter, with high graphical fidelity and high performance networking. These things are the key features of the Unreal engine, which is why the engine has the cons and pros that it does.

In Unity’s case it was designed to be nothing but a game engine that would not limit game developers in what they could do, and eliminate the many bottle necks in the game development life cycle. It is simply a product built to make any game, not a particular game.

The differences between the two are seen in the usability of either one the engines. This is most prevalent in the languages that they use. Unity uses C# (aka Microsoft’s Java) whereas Unreal uses C++. For beginners and even intermediate programmers writing effective C++ code it very difficult. Since there is no memory abstraction layer and the syntax is not as initiative to understand. Another point of difference can also be see in the minimum computer specifications needed to effectively use the engines. Unity for the most part does not require much, it could probably run on a potato. Whereas Unreal requires a quad core (i7 preferably), 8GB of Ram (preferably more), and good video card (preferably anything greater then a GTX1060) .

The differences highlighted above also explain where the two engines are usually used. After a while Epic Games started to licences out their engine. The licences were very expensive so naturally the only people that bought it were other game studios, who then made AAA games. Unity on the other hand had a free tier and inexpensive (comparatively speaking)  which lead a lot of indie developers to adopt Unity. Indie developers are usually tiny teams working on shoe string budgets. And they are usually content with their profits if it is just enough to make another game.

The biggest difference has to be the community of either game engine. Unity has one the largest and helpful communities out there. There are a ton of forums, blogs, books, and video tutorials out there on Unity. And then there is the asset store, a market place that allows developers to sell anything and everything one would need to make a game, wither it be art work, scripts, or even music the asset store has it all. The Unreal engine has something simpler however it is  not as robust as  the Unity asset store.

It is in my opinion that if you want to make video games you should use what make your feel comfortable. If your a experienced C++ developer looking to code games and have a few art friends to make high rez 3D models, and you want this to be a PC only game choose Unreal. If your a one man developer that has some coding experience choose Unity.
