Not much. But even his bare bones efforts are creaky at present. The stuff is, I repeat, 20 going on 25 years old.
I can pretty much get exactly what he does for 1/2 the price, on steam and with PBEM++ support elsewhere.
Or I can play the stuff I have of his from 15 years ago (which I don’t anymore) if I get the hankering to play his stuff again. So why would I give him 60 bucks (non-refundable) now?
Heck, I can play Kasserine on my Ipad with the App conversion for PzC that I bought 3 years ago for 4.99.
Dropping 60 for a few scenarios doesn’t seem worth it anymore.
