Pro Designed for everybody
Construct 2 is a tool for not just programmers, but artists as well. You can create a game with only visual coding, which is easy to learn and doesn't require any prevoius programming knowledge. You can focus on making your game better instead of just coding. It has some limitations of course, but it's definetly worth it.
Pro In-depth event system
Construct 2's event system allows for deep, detailed control over all aspects of your game. You aren't limited to just a few options. Rather, Scirra has thought of nearly everything in advance with access to any desired parameter of any object all paired with simple and intuitive ways to interact with them. Your events can be organized with event sheets (that can be included in other sheets), event groups, sub-events, loops, and functions that make the coding portion of your game as efficient as possible. You don't need any programming knowledge, but if you do have some, you'll feel right at home with the freedom C2 offers.
Pro Allow server-less multiplayer game creation
Construct 2 uses WebRTC technology to support it's multiplayer functionality. The nature of the technology allows peer-to-peer connection which does not require game developer to create server side architecture to allow communication between games.
Pro Export control for all major platforms
All platform exporters are part of the subscription. There are no additional fees and new exporters are added quickly and maintained well. Currently, 15 platforms are supported, including HMTL 5, iOS, Android, Windows, Chrome Store, PhoneGap and Scirra.
Construct 2 is available in 4 variants. There's a free version with limited functionality that prohibits from making money from C2 creations and a full version that requires either a personal, business or educational license.
