I meant the list of games I had on this particular machine, which only included one multiplayer game registered via impulse. I thought maybe it was trying to give me a hit that I don't really need RtP 
well, with the number of SD fanatics it shouldn't be too hard to round up 5 or 10 that will go through newly-released games and edit whether they are singleplayer only for free D:
Ah, but if a mistake is made? There'll have to be some function for disabling the "singleplayer only" filter, etc... probably better than as-is because some idiots will look at it and say "yuck, yuck, Stardock doesn't realize GC2 is singleplayer, lets go make fun of them on the forums", but honestly preventing that is the only compelling benefit I see from a filter
