What are the capabilities of game engines?

Question

Game development

Is it possible to implement non-standard game mechanics on ready-made game engines? For example, minecraft can be made on unity?

Answer 1

Non-standard? Pretty standard mechanics. I see no problem making Minecraft on Unity.
And, in my opinion, there is even such a one, Block Story, if I'm not mistaken.

Answer 2

It depends on what engines (and what is generally considered an engine). On Unity3D it is possible, on Construct2 - hardly.

Answer 3

Does it fit into flowchart algorithms? So - it is possible. The only question is labor costs.
