This is going to ultimately be the final nail in Unity’s coffin. Epic has changed the game with the new model for UE4: Point for point Unity cannot compete (not even Unity 5, they are just getting around to adding a small set of features already available in UE4) , and almost everyone that uses Unity needs 3 or 4 extensions to it in the form of asset store addons to make it a complete solution. Don’t forget the non-trivial stuff that UE4 has out of the box that Unity 5 still lacks: actual network replication and prediction with an authoritative server architecture, game behaviour trees and AI frameworks, material shader networks, and more.
The only thing missing is a central market place / asset store for the community to blow this whole thing wide open.
I’ve been making games professionally for over 15 years and it’s been a long time since I’ve been this excited.
In a year from now the UE4 marketplace will be huge: you will be able to download asset libraries and game templates and frameworks that will get you started with any crazy genre you can imagine, RPGs, myth style RTSs, puzzlers, boards games etc, with just a few mouse clicks.
Please hurry with the marketplace!
