OpenAI Gym Beta

OpenAI Gym Beta (article)

Excerpted from the OpenAI website:

We're releasing the public beta of OpenAI Gym, a toolkit for developing and comparing reinforcement learning (RL) algorithms. It consists of a growing suite of environments (from simulated robots to Atari games), and a site for comparing and reproducing results.

OpenAI Gym is compatible with algorithms written in any framework, such as Tensorflow and Theano. The environments are written in Python, but we'll soon make them easy to use from any language. We originally built OpenAI Gym as a tool to accelerate our own RL research. We hope it will be just as useful for the broader community.

Open source, MIT license (free for private / commercial use with MIT license inclusion)
Available on GitHub

NOTE: unlike other FOSS spotlights, this software is in public beta.

Ren'Py

Excerpt from Ren'Py website:

Ren'Py is a visual novel engine – used by hundreds of creators from around the world – that helps you use words, images, and sounds to tell interactive stories that run on computers and mobile devices. These can be both visual novels and life simulation games. The easy to learn script language allows anyone to efficiently write large visual novels, while its Python scripting is enough for complex simulation games.
