You use a program called "textractor" and couple it with "Sugoi translator". Textractor will grab the text from the game and sugoi will have it translated from Deep translation. Google and Bing are horrible in comparison.
If you set up translation you can actually read the fandisc also. Translation will be far from perfect, but will be overall very accurate and little nuanced with some quirks here and there due to processing errors. I read tsujidou san fandisc like that and it was quite alright to read and i understood almost everything.
Planetarian and Narcissu are usually the ones people recommend to beginners. Also Saya no Uta, if they're into this kind of stuff.
If they are more into the literature side of the genre, I would strongly recommend Adabana Odd Tales. And if they are into yuri, The expression Amrilato is also pretty nice.
Taking a break from MAMIYA and playing Togainu no Chi. Just finished Rin's route and honestly I really didn't like him at first but now he's my favorite, lol. I really enjoyed his route. I really wanted to like Keisuke's but it kinda just fell flat imo. Ended up not liking Keisuke that much in the end.
