They're already pretty close to their goal with still 30 days to go.
From the campaign:
Death & Taxes is an adventure for 4-7 players using characters level 4-6. Although designed for classic rules, the ultimate goal is to create total conversions of the game for popular modern systems. Once the goals for project funding and the backer surpass the initial stretch goal targets all options are on the table, As backers, you will have a seat at that table to decide which one will happen first! Look for the results to be revealed in our Stretch Goals section as the campaign progresses. The Gnomes are ready start to translating Death & Taxes into Pathfinder/OGL and (we hope) fifth edition compatible versions.
