Yeah, I definitely like building a larger list, but I think the "all killer" is a good tool. It leaves off too many older titles for my taste, however.
As far as the Maximus gui, when I drop the .txt file on it, nothing happens. No report or .lst created. I also notice that if I go back to the "supported files" box later, after running an export to LB, if I drop down to Maximus Arcade, it doesn't change to the location of the Maximus related files... stays on location of LB .xml.
