I am seriously excited to try out Construct 3, as it enables creation of games without actual coding. It uses an interesting events system like in Construct 2, Fusion and other toolkits. The developers have shown the first preview with pictures of it on Linux too.
Godot, the open source game engine for 2D and 3D games is going to get a brand new 3D rendering system and the developers have given some updates on it.
Unity 5.5 has been released as a pretty major update to this popular game engine. One interesting bit for us is that games built with 5.5 onward will only have access to the modern OpenGL system.
xoreos is a FLOSS project aiming to reimplement BioWare's Aurora engine (and derivatives), covering their games starting with Neverwinter Nights and potentially up to Dragon Age II.
Clickteam are the company behind some really cool tools like Fusion, previously called Multimedia Fusion. They did an AMA today where a developer noted their Fusion 3 editor is running on Linux and other platforms.
OpenMW 0.40 is the latest release of the open source game engine for playing Morrowind. It's crazy how far along it is now, close to feature complete by the looks of it.
After almost six months of hard work, we are proudly presenting you the marvelous Godot Engine 2.1. Just like 2.0, this version focuses almost exclusively on further improving usability and the editor interface.
It's definitely great — and not that usual — when developers are prudent enough to conceive their games from the ground to be multi-platform. That appears to be the case with the developer of the small studio Cold Beam Games.
