There is also Red Info which is Robert Kurvitz, Alex Rostov, Helen Hindpere and Martin Luiga. They are apparently working on something and will probably make an announcement next year (according to Martin Luiga on his recent Human Can Opener podcast appearance).
Unity is flawed, but somewhat of an underrated gem. It’s such a shame that it released in the state it did and got the reception it did because that’s pretty much what caused Ubisoft to pivot into the style of the Origins and onwards style games.
