I'll start with the more annoying thing about this game: The items/characters powers. There is TOO MUCH stuff that gets thrown everywhere at once, most of the time you'll be hearing the warning beep, well, beep all the effing time, and be hit by basically anything since most stuff homes into you or some tracks are so effing small and cramped that it's basically impossible to dodge something (Those FF9 ones, ugh). It would maybe be just irritating if it wasn't for the fact that most of these attack get you to a complete stop, and others even make that stop even LONGER. It ain't fun being hit back to back, unable to basically move at all and end up from first to last just like that.
Next I'll rant about the characters: Not really how some are, welp, uninteresting or what, I kinda grown into a lot of them, but how most are basically unuseable outside of the simpler tracks: Unless the char has an higher than average handling, even when drifting you can barely make most turns (braking barely helps), and on those more cramped and twisting tracks, playing as an all speed char feels like an exercise in futility. The best characters are the ones that share the same stats as Steiner's: Everyone else is either too slow or can't turn to save their lives.
Now them tracks: Some are fine, some are a pain until you learn them, and some are just awful, horrible. The Alexandria tracks are some of the worst I've ever had the displeasure to race on. Even with the aforementioned best chars it's just a pain to race on those. There's basically any room to race, like, the road is barely big enough to fit two chars side by side, so, you gonna constantly bump into everyone, losing speed, and dodging attacks is basically impossible. There are constant 90° turns that just are so infuriating since the road's not big enough to swerve around unless you're at a perfect angle, which, seeing how chaotic everything is, is basically never. But the main problem with the tracks of this game is how most are so effing short, even the longer tracks aren't as long as the damn first track from the first game. Some don't even take a minute to finish. It just makes the game feel even more shorter than what it already is. Oh yeah, also: Too many effing jumps which end on really tight curves, making those really a pain if you trick off them and the burst of speed kills off your turning.
Regarding items again: I'm not a huge fan on how they changed the looks, like... in the first game, you could actually see which ones you could get along with random "?" ones, so you could either go for the one you wanted or try to gamble or something. Now it's all random, so, if say you're in first and want shields, or just want something specific, good luck. Still, suppose having the gold ones giving you two of the same, the silver ones give either a random or add to the one you have and bronze be completely random is somewhat alright too... Guess this one's not a huge point, but just felt like talking about it anyway.
Guess last point I can talk about is the music: Most tracks sound pretty gud, FF did always have some really good music, but whoever decided that the menu music had to have vocals should have headphones glued to their ears and forced to listen to that music constantly at max volume. At first it's maybe cute, but then it gets GRATING to ear it all the effing time, ugh. Now for some time I'm never gonna get this dang vocals out of my head... Also, the credit music is... fine, but is no "Diamonds in my heart". You can't top that one.
Guess one last thing, but this is just me: While the char look... fine, I wish they didn't just go for the overly cutesy look, like... Chocobo's cute, but was also cool too, he and the other chars looked fine in the ps1 days, now most are just too... sweet, meh.
To finish... It's disgusting what SE has done with the game, and a shame it came out so... unpolished. It ain't no Crash Team Racing, even Mario Kart is better than this, as much as it pains me to say it, MK being the bare minimum to surpass to be a good kart racing game. Well, I'll end with this: Fuck you Squeenix, just how fucking awful you've become since your glory days... Shame on you.
