The idea is really simple, every model painted will earn a pre-determined amount of points as detailed below.
25mm base = 1 pt.
Character + 2 pts.
A completed unit of 5 Space Marines that have been based and transfers added would earn 10.5 points giving me £10.50 for my hobby fund. Obviously this is great but to purchase something better I would need to make a small piece of terrain / scenery to give me an extra 10 points totalling to £20.50.
12 Kroot (that I have had for years), if painted and based would earn 20 points adding £20.00 to the hobby fund.
A completed Razorback with Transfers and both types of Weathering would earn 20 points adding £20.00 to the hobby fund.
