Never read Dune and barely remember the original movie. Trailer for new ones looks fantastic though so might follow your recommendation and try the book 
FF7R was my 2nd best game of last year after The Last of Us Part 2. I might be biased though as first TLOU is my favourite game of all time I also started a 2nd play through of FF7R but had no MP against hell house so impossible to defeat it (had found rest of Hard mode easy untill that!)
P.s FF8 is my favourite of all time and the theory is it's always the first one you play... which it was! Series really dropped off after 9 though
Agreed the new Dune trailer looks great. I like the director as he did Arrival (great film) and Bladerunner 2049. It is an expensive movie and Hollywood are apparently nervous it might bomb a the box office and people would rather see a Marvel film or Ghostbusters rather than a film with a complicated storyline. Tim Chalmanet (sp?) looks brilliant as Paul Attreidies.
I played (and even platinumed) FFVIII over Christmas. I hadn't played it before and I thought it was great. I had 2 weeks off over Christmas with very little plans so thought I'd buy a JRPG to get stuck into. It was great being able to send long hours long sessions playing it.
For FF7R, did you know if you get MP shards from a Shinra you can save and reload your game and the MP shards will be back do you can get up to full MP? I think there are shinra crates in the junkyard bit of Chapter 9. I basically went into every boss battle with maximum MP this way. Also you can get Guttendummach by completing the combat simulator in Chapter 7 which efffectively nerfs all non-boss battles so you don't need to use MP. I didn't find Hell House that bad, I used Bio to slowly poison it and kept healed up. Hard mode really is impressive though, the bosses are all really hard but feel doable! It took me about 30 minutes I think to defeat Arsenal on hard but I had a safe strategy of picking him off from the safety of pillars. I actually beat Sepiroth on hard first go!
I am a bit unsure what to play next. I have PSNow and PS Plus (yeh, bit of a mug I know) and games a bit shit this month so think I'll go back and finish Witcher 3. I also really need to give RDR2 a proper go, it looks great just never seem to get into it.
Have you played Control? I think that will end up being my favourite game from the PS4 generation.
