Négoce - A procedural trading game

WARNING: this game does not have sound (yet?)


  • Click on items from you inventory to send them to the trading window.
  • Click on items in your trading window to send them back to your inventory.
  • The trader may have more than 3 trades; use the "scroll bar" to see the other available trades.
  • When the trading window contains items that match the trader's interest, the corresponding trade will be selected in BLUE and the result will appear in your trading window.
  • Other trade that can be made will be highlighted in GREEN; click on them to select them.
  • Click the Trade button to trade items with the trader.
  • Click the Next tarder button to switch to another trader with a different set of trades.

Made for ProcJam 2015, Négoce is a game in which you trade items to reach a specific objectives. Trades and objectives are regenerated each time you play. The game was inspired by a game I played as a child (except the French version has better voices).

On the title screen, you can adjust 5 parameters for the trade generation :

  • Chain size will determine the vaerage amount of trade each trader will propose
  • Traders will determine how many additional trader will be added to your game
  • MaxInput will determine the maximum number of items you will have to give in a trade
  • MaxOutput will determine the maximum number of items you will receive from a trade
  • Objectives will determine the maximum number of objectives you will be assigned

The next play will start with whatever inventory you were left with last time ; your inventory will be reset if you return to the title screen or close the window/tab containing the game (doing so will also reset the successful trades score).

There should not be any game-breaking bug left in the game ; however, if you find one, do not hesitate to post a comment about it!

Lovely graphics, I had fun. I included it in my ProcJam compilation video series, if you'd like to check it out :)

This is really good but also a bit too random. It can get really easy sometimes. I wish the difficulty was a bit higher (moving the parameters up add complexity, but not difficulty)
