Thank you very much, and I agree that even though it can be nice that the game doesn't have frequent releases, I would enjoy a little more activity from the company in terms of news and promotional stuff.
The last news article on the website is from January 2017, about their painting competition. Before that, the last design spotlight, that talked about a model in the game, is from November 2015. That's not a lot of traffic of promotions.
Over the last few months I bought and painted up some Shadespire warbands myself - a game that seems heavily influenced by Arena Rex, in that it uses the same "roll attack dice as a contest vs. defense dice" mechanic that AR does, and promotes itself as a "game of tactical arena combat". It was fun to do and play a few games of, but I prefer AR, even though I like that SS uses a hex board.
Ladon and Cato seem really cool, so that is a new release I am happy about. I think I will probably end up getting Atrox too some day. We'll see about the Helleniki.
