Tandi's good, neutral and bad reaction images

Character reaction is a game mechanic in Fallout and Fallout 2. It reflects general attitude of an NPC towards the protagonist. The reaction can be good, neutral of bad.

Reaction value is composed of two components: base reaction and static reaction. Base reaction is preserved between dialogues while static reaction isn't.

Initial reactionEdit

Initial reaction is calculated from multiple factors:

Characters marked as "evil" have their reaction modifiers from reputation titles (except Childkiller) backwards. Slaver title's effect sign rather depends on what the character thinks of slavers.

In only a few locations are appropriate characters marked as "evil" for this purpose in Fallout 2:

Changing Edit

Reaction is changed by saying nice or mean things to the character by choosing appropriate dialogue options. For talking heads, the character's expression visibly changes.

There are also scripted changes by various amounts.

Under the hoodEdit

It's an integer from -100 to 100, with 25 and higher for Good, -25 or lower for Bad and Neutral for in-between. There's also a separate variable from -4 to 4 holding just the level. After one is changed, the other is converted to reflect the result. Both variables are recalculated each time a conversation starts, only the base reaction is saved.

Base reaction:

  • On the first conversation: each point of PC's Charisma over NPC's: +5 (if higher) / -5 (if lower)
  • After that, it's only altered by scripted changes

Initial static reaction:

Changes:

  • The dialogue options adjust the level by one or two (?).
  • There are also scripted changes by various amounts as well as direct assignments. They can affect either base reaction or the effective reaction.

EffectsEdit

Compared to how much thought was put into the reaction system, it's largely unused. Only for few NPCs does it affect the course of the dialogue (39 in Fallout 2, to be exact). The most prominent effect it has on gameplay is affecting barter prices (e.g. in one test, for Chitsa (CH 10 and Sex Appeal), Leather armor was offered for $1218 by Maida Buckner and for $1190 by Sajag).

A possible reason may be that it's proved to be excessively restrictive. There are few ways to improve an unfavorable reaction once it's established, so it would only frustrate the player by erecting unpleasantly surprising roadblocks, potentially at any interaction and any step of any quest. Though it's highly unlikely this would render the game unwinnable, it may still deny the player critical clues and ruin their experience.
