I really dig this thread! Japanese PCE artwork is all over the TG 16 ones.. A Huge example for me is Tiger Road
Yup, Tiger Road is one of my most hated Turbo covers, not even counting the PCE version. What is with those weird, awkward, 2D pencil drawings for 80s and 90s US games? Where were they finding all these terrible artists?
That said, I actually do prefer a few of the US covers, including Chew Man Fu (I've just always really liked this one), as well as the 2 Bonk covers, which I think both look great. However, Bonk's Revenge always kinda looked like Bonk was smashing an innocent dinosaur.
