As a company, we like to say that we iterate on our game—a lot. There are three different ways that we can make changes: we can remove things, we can change things, and we can add things. Luckily for anyone playing the demo a second, third or twentieth time, we have done all three of these things to many aspects of the game.

For me, the best part of these demos is how they let players see the iterative process. From PAX East and the introduction of thief, to Comic-Con where we tried an initiative system with cheaper costs and slower regeneration, and to gamescom where the thief will use the original numbers once again. I’m sure that people are theory-crafting on which is better. Thankfully we don’t have to theorize; we can play it and see for ourselves. The slower-regen idea seemed so good on paper, but in practice the original design was just more fun. As we roll into this next demo season, there are a few major changes that we thought we should tell you about, and without further ado, here they are.
