This is Eiyū Densetsu Sāga (Arrow Soft/Micro Cabin, 1984) for PC-88/PC-98, and it's probably one of the first ever computer games to use scanned traditional illustrations instead of pixel art drawn on a computer. But because it's 1984, you only have eight colours and a very low resolution. The resulting imagery is recognizably different from something done pixel by pixel, but it doesn't look like you're looking at a painting instead. It's a bit soft, a bit unreal. It feels like a scene from a dream. I love it.
