Before you open this up to steam take a look at the Fallout 4 forum over there right now. If you put Aces High on steam, yah we might get an influx of new targets. But the IQ level would drop down tremendously, I'm talking all the way down to 49er levels.
Based on personal experience the IQ level of the average AH2 player isn't exactly on the high side either. If something can bring in more players then I'm all for it. The whole "keep AH2 a closed club to only the most elite of WW2 sim players" isn't going to last.
