Sorry never saw this thread.
I would say yes but not right now.
Leader boards and rankings are possible if you have some sever side scripting knowledge. If you do not im happy to help.
There is also a third party plugin called Playtomic which will store data from your game, But it also has online leaderboards built into that, which is really easy to use.
Multiplayer is not possible right now unless your a genius at scripting.
But luckily there is a genius in our community who is currently developing a multiplayer plugin. he has posted videos of it working! and its available pretty soon he reckons.
So stick around.
As your new to Construct2 I suggest playing around with it for a while, getting to know the ropes as a board game will be pretty intense to work on even in a simple game engine like this one. You will need to understand arrays.
We have a really good friendly community here in which many genius's are allways welcome to help(im not one of the genius's) But im always happy to help, Im pretty good with the engine.
But yeah give C2 a go, And welcome!!!
