I am curious what everyone will be using to create their games. I am planning on using Python and the Simple Python Game Library (which I wrote).

I'm probably going to use Unity for this one as i'm most familiar with it. If not, i've always wanted to try out SDL2 with C++ and see how far I get with that.

C# & Monogame

GMS2!

Game Maker v6.1

Godot Engine for the game, Aseprite for art, Caustic for music/SFX.

I'll be using Gamemaker Studio 1.4

JavaScript. Notepad++. Paint.NET. I'll wait and see what style develops before I think about my audio/music.

Getting my hands dirty with low-level OpenGL in Go :D

We're also using Go, but a lot higher level: https://github.com/oakmound/oak (we also wrote this engine)

I haven't decided yet. My two games I have completed were with GM:S 1.4, but I did want to get into PICO-8. 

I'll may be using SFML / C++

I'm using Godot 2.1 and a really outdated version of gimp.

Javascript with the Hermbit Engine (obviously written by me)

I am using Python3 together with pygame. I'm alreay femiliar to this setup because of my current long time project.

Lua LÖVE, my personal favorite...
