This year is special for all Poles. Steam wanted to celebrate with us, so they organized a 'Polish Developer Sale" sale for the 100th anniversary of regaining independence by Poland
Therefore, you can purchase many games from Polish developers at promotional prices.
Ultimate Fishing Simulator will be on sale a bit longer - until November 12.
