The Il-2 series also has a slew of medium and light bombers (and one 4 engine dinosaur from the 30s the TB-3), the He-111, Ju-88 (can dive or level bomb), Betty G4M (IJN), B-25, A-20, Mosquito (only the FB version flyable) and the Pehska Pe-2. They come with bombsights as well, quite fun and a change from shooting stuff down. Sadly, no real heavy bomber game around since B-17, someone was developing a sim centred around the RAF night Bomber Command ops but that became vapourware sadly.
