I love this game, and enjoy reading HopesGaming's posts. He/she's a talented developer.
That said, the updates are very long, and I don't think it's fair to say that they're consistently keeping to a 2-3 month release schedule, with the only exception being the release of v.5 due to personal life problems (totally understandable).
The last update was almost 5 months ago now (September 27th). The November update was simply extra languages, and I feel it's disengenious to state that update as the last gameplay update. Thread updated and last update may say November, but in truth v.5 came out September 27th.
Not too bothered by it though as I don't really follow this game anymore, but rather will stop by the thread about once a month, and in the off chance an update is released, I get to thoroughly enjoy this brilliant work of art.
