### 3/5 — Playable with some thought

*2026-06-26*

Faithful and working board game implementation.  If your playing solo you might want to win the tech auctions for 0 at lest initially. A bit clunky with options buried in menus. I get fun out of it though.

### 1/5 — Incomplete

*2025-01-17*

This game is still in alpha relative to a full implementation of the board game. Do not buy at full price and allow yourself to pay to be an alpha/beta tester.
