Can I make an entire game in blueprint?

[=wburton;212833]
Give me an example of what I can only do via C++ solution?

In what way would blueprint be limiting?

Voxels require dynamic meshes, which blueprint doesn’t yet support.

There are tons of little things that are really game specific where you would want C++ over blueprint. Some are performance related, and some are due to lack of functionality in blueprint.

In general, you can make a game similar to just about any game out there using only blueprint. It is the finer details of execution in specific cases that is often what you would find lacking in blueprint.
