The newly reborn Microprose is remastering a bunch of the old titles, including the B-17 titles. Their new titles are very good. I especially like, "Regiments". I'd definitely recommend it.
Maybe we'll get lucky and they'll decide to remaster, "Gunship!" and, "M1 Tank Platoon II" for us. I spent a lot of time with those titles back when they were current. Perhaps, "Silent Service" will get remastered as well.
