"Geneforge"'s dialogue is delivered through on-screen text. Encounters with intelligent creations or humans result in the player being given a series of pre-determined questions or responses. Conversation options and the outcome of those conversations change according to the player's previous interactions. as well as which quests have been completed; which items the player has; which group the player belongs to and the player's leadership skill. The player can collect items from defeated enemies and the game environments to improve their own equipment. Non-player characters can trade with the player, buying most items regardless of type. The shopkeeper has a fixed amount of gold at the start of the game which does not replenish itself. It is possible for the player to drain all shopkeepers of their gold reserves, making it impossible to sell further items.
