Pros
Pro Enjoy creating and playing your own game or thousands of other games available
You can create your own original game and play it, and have others play your game too. As of 2017, Roblox has over 500,000 game creators designing games. That's a lot of games made by players like you, so you'll never run out of options on what to play.
Pro Gives more flexibility when it comes to building
Since creations are not limited to cubes, you are given more choices. Players can fully customize the size of the blocks, and make wedges and hills that are not cube-like.
Pro The game is free to play
You'll be able to create your own games and play without paying for anything. Though they do have virtual currency that they call Robux, which you have to buy with real cash. You only have to do so if you want to upgrade the look of your avatar or get optional in-game power-ups. Like with most games, if you have the patience you can additional items over time, then you don't have to spend a dime.
Pro Offers a safe chat mode for kids under 13 and a parent's login
Since Roblox is used mostly by younger players, a primary concern for parents when it comes to interactive and multi-player online games have always been the safety of their children from online predators and inappropriate behavior. Roblox has this covered with their safe chat mode, and a parent can also monitor their child's activity and account settings.
Pro C# integration
CryEngine has some C#template and also C# based system to write your function/ideas in to your game.
Pro DX12, Vulkan support
CryEngine 5.4 now supports DX12 and Vulkan
Pro Features allowing for realistic weather effects
Cry Engine has volumetric fog rendering which allows for realistic cloud shadows that actually render shadows onto the fog itself. Combined with their time of day system, it's possible to create incredibly realistic weather effects. On top of this, color grading allows user to post process pallets allowing them to change the color tone for different type weather, such as using a deep dark blue for rain.
Pro There is already a built-in AI
It can shoot, walk on patrol points, can see the player and so on.
Pro VR support
Cryengine (starting on Cryengine V) has Virtual Reality support. Developers can create games with VR support for multiple platforms: PlayStation VR, Oculus Rift and HTC Vive.
Pro Dynamic water rendering
Cry Engine has realistic water effects that even simulate ocean physics. Features such as waves that respond to global wind, and dynamic water volume tessellation allow for some of the most realistic water effects available to a game developer. The engine also takes into account LOD (level of detail) on water geometry to allow it to stay performant for water at a distance.
Pro Realistic rendering of vegetation and landscapes
Where Cry Engine really shines is with rendering scenes of nature. The Crysis games feature incredibly detailed vegetation and weather effects and it's the Cry Engine that enables that. The engine has many features to create a cohesive realistic looking world. Dynamic water effects allow users to have beautiful oceans, fog and cloud effects allow for realistic weather, and a plethora of lighting effects optimized for natural looking scenes make Cry Engine one of the best engines for creating vast beautiful landscapes.
By having all these features built together from the ground up, Cry Engine is capable of doing more complex effects more efficiently, than other engines that didn't have these effects planned from their inception.
Pro All platforms, including next-gen consoles, are supported
Supports miltiple platforms including: Xbox One, Xbox 360, PS3, PS4, Wii U, PC, iOS, and Android.
Pro Versatile flow diagram script model
Flow graphs resemble flowcharts where each box represents a function or value, with connections between them representing program flow. This provides a better at-a-glance indication of game logic than a simple list of events, and makes complex behaviors easier to accomplish.
Pro Dedicated channel for Q&A
Crytek has launched a dedicated Q&A forum for everything Cryengine related. It's called Cryengine Answers and it's a community dedicated to sharing and answering any question related to Cryengine.
Pro Online marketplace available
The Cryengine marketplace is an online marketplace which enables developers to access and use individual assets from thousands of materials, sounds and 3D objects created by the community. Even Crytek's own library assets are available there.
Pro Advanced volumetric cloud system
Cryengine has an optimized volumetric cloud system for Virtual Reality to give clouds full 3D spatial rendering. This ensures a high rendering quality with a minimal performance hit.
Pro Terrain tools are great
Pro Disallows bad practices in asset creation
Simply by looking at the RC log when exporting can greatly improve your work. Cryengine doesn't handhold you constantly and helps greatly with avoiding bad practices in asset creation.
Cons
Con Steep learning curve
Except for basic FPS games getting anything done will require solid knowledge of C++, Flash, ActionScript and Lua.
Con No GNU/Linux support

Con Hard to develop games other than FPS
Cryengine is a great engine to be used for developing an FPS (and it's relatively easy to do so). But if you want to develop another type of game, it requires at least advanced knowledge of C++ and Visual Studio.
Con No Mac OS X support
Con Restrictive license
Cryengine is not restrictive anymore just more personalized. The model is Pay what you want and if you want more you get a membership with them. Or private support, help and lessons directly from the CryEngine team.
