The holiday sale came, unfortunately there are no achievements, but there are always hidden gems to be surprised at!
Will add any game you suggest as long it's not a daily deal/flash sale/community choice. Please include the game's link as I may not add your game depending on my mood and on Steam website's traffic.
Any of these games might get a steeper discount, so specially for the least discounted games, waiting till the last day of the sale is advised. Prices are shown in USD. Games with a discount variation of 1% will not be created in a separate list (i.e. 65% off instead of 66%).
