I guess this is a feature request.
A number of games have this, and benefit from it in early access in particular. For this game it might look like this.
The game starts as normal, though instead of arriving at the Spaceport, you arrive at another refugee camp. You proceed to make a selection like you usually would as to the type of terrain and main enemy, but the game essentially feeds back through another procedural map.
We might be seeing the same few story areas over and over, but that goes with early access.
The main benefits of this are that it *shouldn't* be too hard to deploy, and it would allow for more effective playtesting. Right now we appear to be playing through the first two maps of the story mode repeatedly. I've seen some enemy decks only once, like the..."Five finger..." I can't remember that zone or faction. I got killed.
This would also help test save/load fidelity a bit.
If we can have essentially unlimited play through samey but procedurally made maps, we can test out an increasingly large number of card combinations, how they fare against different enemies, and how such a mode would do in the long run.
Finishing the story mode is part of the long plan, we know that.
Your hard work is highly appreciated and personally, I want to thank you for it. This game is filled with love and care and heart. It is a real gem. A "nowhere mode" would let us wander in your labor of love for endless hours, both before and after the story arc is finalized.
