You could try reading VNs, those are basically books but with some illustrations and a soundtrack. And maybe if you get used to that then maybe the transition will be easier. Plus visual novels are just really good in general, its a shame they're not more popular.

Well, as a caveat to my description of VNs, there's quite a bit of variety, and in the west VN also gets used as a description for a shitty rpg. But the things that would be called 'novel games' are what I am talking about. Something like Fate, House in Fata Morgana, White Album 2.
