They are decently high-budget to make up for it though. Full (japaense) voice acting for every piece of dialogue, including the protag's internal thoughts when you examine stuff, animated HD sprites, backgrounds are always well-detailed, and the music is great. The remakes even let you switch the OST of the famicom versions (and the OST of the super famicom remake of the second game)
