Galaxy options control the galaxy's extent, boundary behavior, and features assigned when a sector is generated. Classic and ge-next defaults are compared in [[Main configuration reference]]; ge-arena uses its own main MSG file. This page explains operational consequences rather than repeating every option's default.

== Dimensions ==
<code>UNIVMAX</code> sets the intended radius in sectors from 0 0. The intended dimensions are therefore <code>(2 × UNIVMAX + 1)</code> sectors on each axis. Classic GE has an edge error that prevents those intended bounds from working consistently; ge-next corrected it. See [[Classic bug: Galactic perimeter edge errors]] and [[Galactic perimeter]]. Changing the radius after sectors or ships have been stored can leave records outside the new boundary. A new radius should be introduced with a fresh database or documented migration, not a casual live setting change.

ge-arena is different: it sets the radius at match start to five sectors per entering player and wipes the match galaxy afterward. It also scales scanner range to 50% for two players and 75% for three; four or more use the normal range. Later departures do not resize an active match.

== Boundaries ==
<code>UNIVWRAP</code> selects wrapping to the opposite edge or the galactic-perimeter response. ge-next 0.3.2 bounds its speed-dependent bounce for small configured galaxies; see [[Galactic perimeter]]. Wrapping does not change which sectors already exist.

== Generated features ==
<code>PLODDS</code>, wormhole odds, and nebula settings affect newly generated sectors. Once a sector has been stored, changing odds does not reroll its planets, wormholes, or nebula status. Generation factors are not necessarily direct percentages: a sector can enter the planet-generation branch and still receive no planet. <code>MAXPLSE</code> sets the maximum body count, but classic generation has an [[Classic bug: MAXPLSE is off by one|off-by-one error]] in that count. See [[Sector]] and [[Wormholes]] for the creation path.

The nebula seed gives a persistent game a repeatable distribution. ge-arena uses a separate in-memory seed for each match. Disabling or changing nebula generation is not a retroactive edit to existing sectors.

== Record limits and sector 0 0 ==
<code>MAXPLREC</code> limits growth of the planet database. A generated sector uses a sector record plus records for any planetary bodies. If the limit is reached in classic GE, normal creation can fail; see [[Classic bug: Planet record-limit failure]].

Sector 0 0 and its neutral-zone planets are initialized separately from ordinary random generation. Their names, owners, coordinates, and stock are configured in the main file. See [[Neutral zone]], [[Zygor]], and [[Tahanian Station]].

Before changing a live galaxy, back up the complete database set; see [[Database files]].
