Can you make a complete game using blueprints?

I was amazed to see what is possible to create with the new blueprint system.
The big question for me is if I can create a complete game with blueprint, without the need to enter the C++ code.
Including all game UI etc. If not, are you planning to make this possible any time soon?. Maybe some additional tools that will make things easier?, like coherent-labs.com(UI) plugin or fpscontrol(Unity) for instance.

The reason why I am asking this is because it is important for me to develop a game without the need to hire programmers.
Another question, can we use parts/combine or replicate the blueprint script in the samples, available in the marketplace in our own games?

Yes it is possible, but i depends what kind of game you want to do and features in it, with blueprint you can do a lot of things, pretty much you can do all kinds game types, but sometimes you might hit lack of specific feature in blueprint, for example blueprint lacks system clock access and time framework that there is in Unreal APis but only on C++. There weirder and complex game you gonna make the higher chance you will hit hits kind of wall.

As for UI the only current solution in stack is use HUD canvas or use clickable actors in 3D space (which is only suitable when you making game on one place of the level, like Tappy Chicken or Memo game), there is UMG coming which is blueprint support for Slate (Unreal’s UI system which currently is only avabale in C++), it will be added in few months (if everything goes ok). You can also use coherent UI but im not sure how easy it is to use :stuck_out_tongue:

This question has been asked many times.

Yes, a complete game can be made in UE4 using Blueprints only. To my knowledge there are a few networking functions currently only available in C++, but Epic has stated they intend to make those available in Blueprints.

Games are difficult to make, so that does not necessarily mean that anyone can make a complete game.
