I have no idea if it's one of the engines Fargo was talking about with us earlier, but Unigine Corp CEO Den Shergin tweeted he is offering a free license for the Unigine engine to inXile for Wasteland 2. According to Shergin, inXile is evaluating the option now. We've contacted Fargo for comment. Unigine is a multi-platform (Windows, Linux, MacOS, PS3, Android, iOS) engine. It is best known for Heaven benchmarking tool, and I don't think it's been used on too many released titles, though there is Unigine Corp's own Oil Rush, intended to be a small release and engine demonstration. See some gameplay here or listen to Total Biscuit talk about the engine and game here. The system requirements of Oil Rush are really low (2 GHz processor, 1 GB memory, GeForce 8600/Radeon HD2600), so that's a plus. See some benchmarks of the engine here. Phoronix discusses some of its strengths and weaknesses as a multi-platform option here. Worth keeping an eye on.
