Great pixels there, Mustawd. Dope that you are into the IceBlink engine as I discovered it about a year back and didn't hear/see much of it since then. I believe it was Dorateen who informed me about the work being done on the larger module, Hearkenworld, but I'm not sure what became of that. I may even take a crack at learning the toolset as well someday. Keep us updated on this.
As for the Steam Controller, I love the damn thing. I mean, define "effective", because I'm pretty straight with the controller by itself. Currently playing NWN with it and it's great. Since NWN doesn't support the Steam Overlay due to being a weird, modified version of OpenGL, you can't really type too well when naming a save file, taking notes in your journal or naming your character, but everything else works great. As it stands I play NWN exclusively with the Steam Controller and it will be my preferred method of control going forward for all games. You can map all the keyboard and mouse functions to the huge bevy of controls on the controller. It's nice.
