Ever since Star Traders we have built every game as capable of custom difficulty.
Depending on player feedback and reviews on Google Play / Apple App Store, we add custom difficulty when it will help the game. No doubt about it, it is a feature that, when it works, it works well. On some games, the majority of paying players don't care and we don't worry about it -- but it is standard practice in all TB games already (not ST RPG, our first game did not have that code.)
My answer to gundamgoth is the best possible one for the players. As our current catalog of games demonstrates as clearly as I know how, we are very focused on delivery of non-linear progress, emergent strategy and staggering permutational depth. We won't be changing that tradition just to satisfy an XP bonus equation, trust me -- it's five years of work vs. two hours of math on a whiteboard. I'll take the math and keep the philosophy intact
It's not your fault jknut. The no ETA policy has been around awhile. Cory was just over excited with the Alpha release so I didn't flag it like I do with other post and threads. A few of us work as ETA detectors, trolling the forum for them. We have to keep the TB's from going to the Dark side
