Oh Final Fantasy VII is a very big deal for me equally - VII, VIII & IX are my top 3 games of all time! However, I find myself not hyped for the Remake - I have a mindset where I see REMAKES as an indulgence and really I'm more interested in seeing where S-E go with the series after XV... Don't get me wrong, I'm all for it! & I'm getting it Day One, but just not feeling much buzz around it as I would a NEW Final Fantasy title.
I often find Editions have mostly tat & that you can often get better items outside the Editions - Persona 5 had a separate Artbook & Soundtrack while the Take Your Heart Edition offered a sample CD & Thin Artbook. I tend to go for Special Editions if they're no more than £20 over the asking price of the basic game, usually £5-10 if they're just a steelbook.
As for Pre-Ordering, I've had very good experience in doing so, I'd say if you want to get a game within the 1st 6 months you can genuinely pick-up a good deal online (I got the Yakuza Remaster Collection for £35 - New, where as in stores it's £50). I have recently decided to Limit my pre-ordering though, as I find I often buy too many games but don't actually make the time to play them :O So, I'm trying to limit to 5 per year... (Yak Col, FF7R, Persona 5... Resident Evil 3 Remake & Trials of Mana Remake are also tempting me...)
