Pah! self control! (lol) that's always been a strong point of mine...... I kinda think that's one of the reasons we play games though isn't it? To try to break them a little? Me and my friends were having this conversation the other day actually, in terms of the psychological aspect of playing an RPG and grinding to be "overpowered" and why we feel the pull to do so..... It's probably got something to do with being unloved as children (lol) (y)
With regards to Kingdom Hearts, it partly depends how much time you have as the peripheral games aren't as well made in my opinion... KH 1 and 2 are great games but the plot for the whole series is an absolute convoluted mess due to them having to tie into both Disney and Square Enix properties. To answer your FF question, I have played every game in the series but like you (by the sounds of it!) have struggled with the more recent entries. I'll emit the online games as they are very much a different thing altogether FF10 was great - cool music, good plot (apart from the whole "I'm a dream thing"), terrible voice acting though (that laugh! 😬) FF12 is very much a marmite final fantasy. I really liked it and the world / characters are really well realised but lots of people were put off by the almost MMO nature of the battle system and the micromanagement within the gambit system wasn't a big hit with everyone FF13 is my least beloved of the recent entries. The characters just did not resonate with me and I struggled with the whole "run down a corridor for 15 hours before being able to free roam" thing FF15 to my surprise, I actually really enjoyed (lol) I thought the four main characters were interesting and I like the fact that they did a little anime series to introduce each back story. The CGI movie they did for FF15 was a bit naff but it did a good job of introducing the world and the game just kind of assumes that you've watched it for some reason! All of the game systems are slick, the exploration is fun and battling is pretty good but the main issue the game had is its convoluted development which led to the plot being a bit of a mess.... Things sometimes aren't fully explained to the player and some of the "big story events" just fall abit flat... It feels like the developers had to abandon some bits part way through due to square enix essentially pressurising them into keeping the (already slipped by literal years!) release window. Man I should work for IGN 😄
The best final fantasy.
I can't decide which was my personal favorite between 7 and 8, they are definitely my favorite ones. 7 was the first one I played so I'll always have fond memories of it, but 8 just seemed so much cooler when I was a kid. I really enjoyed the junctioning system too, but it was so easy to become overpowered (100 death spells junctioned to status attack) Also abusing the limit break trick, pressing triangle repeatedly until you got one. I really enjoyed 9 as well though, I think that had some of the best mini games. I loved "Chocobo hot or cold" and the card game from 8 made a return (it's been awhile though, I can't actually remember if they improved it or made it worse, lol) I'd definitely recommend giving it a go if you never played it. While it may not overtake 8 as your new favorite, I'm sure you'll still really enjoy it.
But they'd both require a bit of self-control to not use... Actually, I don't know what the mods/cheats are on the re-releases... Makes sense to have though given it won't be the majorities first time through the games.
