I briefly mentioned this in another post. I think that Dan should expand the catalogue into 3 sections, Artifacts, Buildings, and Modules. For each month there would be a new edition to one of these three sections and would be a featured item, and the first month it is introduced it would be "half off" and after that month would be placed into its respective catagory at full price. The way this could work is there are 'Interdimensional Traders' who have foreign technology but they dont accept the standard Galaxy Legions Credits, they only accept GP. This would be another way for Dan to make a little extra money and hopefully be a little more leniant in making the GP more available to the average player.
