Upgrades are easiest to prioritize when each one solves a problem that repeatedly interrupts exploration.
Improve inventory when space ends trips early
More usable capacity increases the value of gathering, exploration and trading at the same time.
Improve travel when distance is the bottleneck
Mobility upgrades are valuable when they shorten repeated routes or unlock more useful destinations.
Improve protection when environments stop progress
Hazard support matters most when it lets you stay productive in places you already want to explore.
Improve scanning when information has high value
Better information can reduce random searching and make exploration more targeted.
