So far Unity is exceeding my expectations in every process.

Creating a game with Unity is quite easy and exciting because you don't need to be an expert in game development. The tutorials and walkthroughs show very clearly each step of the process. Creating integrations with other tools is also a task that doesn't take much of your time.

I didn't delve too deeply into the process of developing complex games, so I haven't felt any lack or difficulty in using the engine. So far the tool is great for me.

I've loved working in this engine for the past 8 years or so -- adding scripts to game objects naturally mirrors the MVC design pattern to an extent. It feels just like putting brains inside bodies, and the whole process is a bit like creating lots of little tiny robot workers to do your job for you and talk to each other. It's as intuitive as playing Checkers; anyone who understands the bare essentials of programming with for loops, if statements, and so forth will have no trouble picking this up. Scripts are small and self-contained -- I rarely write one over 400 lines long, and many are under 200 lines. I've put out a number of casual games with it. Prefabs are useful also -- think of them as visual Classes that you instantiate. You create a game object, put whatever you want on it (scripts, components, children, whatever), drag it anywhere into the window on the bottom center, and it becomes a "factory" that can make copies of itself. One of my favorite code features is the concept of Coroutines -- Unity's way of writing asynchronous methods with a specified delay between one part of a method and another. Want to write an infinite loop that doesn't jam up your processor? No problem -- just create a Coroutine method (type IEnumerator) and add a "yield return new WaitForSeconds (0.5f);" statement inside that loop and it will only iterate every half-second, for example. Unfortunately, cryptic errors outside of my code tend to pop up from time to time, but those usually go away with exiting and reopening Unity. It's also quite a process to migrate your code to a mac for iOS distribution, but isn't it always? Overall, despite the little bugs, slow load times, and over-reliance on plugins, it's a great engine for your 2D or 3D (with each having their own physics systems) game development needs.

-Very easy to grasp the game object / component / script system. -Simple to switch between platforms -C# is a high level language, easy for beginners and advanced programmers to pick up. -Automatic garbage collection (but you still need to make sure it's invoked sparingly) -Great break point debugging system with Visual Studio

-Bloated, slow, and mildly buggy -Plugins will often conflict with each other and give duplicate library errors when building for iOS -Over-reliance on plugins -Not great for web games; OpenGL is extremely slow to load, and it's like Unicron, devouring browser memory

I approached Unity aware of it's biggest faults, and have had an overall easy time getting acclimated to it. It has become my go to tool for rapid prototyping, and each major update has only made it faster and easier to use.

It's hard to best unity for rapid complex prototyping of non-standard ideas. Engines like Unreal can be good if you want a game that fits it's molds, but if you want to break out of the box Unity offers a lot more options.

The outdated user interface, and massive backlog of training material can make it difficult to learn Unity at times. It is much better to find a recent course for an LTE version than it is to simply hit up youtube because quite a lot has changed for the better overtime.

Unity is a very useful program for creating apps and games. For me is the best in the market at this moment. My total experience by using Unity is very positive until now.

Very easy for creating quality apps. The 3d graphics for the games is the best. I add also in the positives the integration with Visual Studio.

The customer support is poor. Most of the games despite the excellent 3d graphics they have too many bugs during the gameplay.
