History YMMV / SonicRoboBlast2Kart

** Accessing the game's OptionalBoss takes more work than you'd expect. [[spoiler:The boss itself is accessed via Espresso Lane, where you need a Spin Dash combined with a Boost to collect a Pogo Spring hidden behind a waterfall and use a Spin Dash to get on the bridge standing just past the starting line, which leads into a vertical tunnel that needs the Pogo Spring and a ''very''-accurate down trick to reach the top. Even after that, you still need to hit five switches using all five bananas presented to you, and both special items ''do not'' respawn, so this requires near-perfect precision to hit all five switches and raise the platforms needed to reach the other side. If you mess up on any of these parts, you have to start all over again to access the area and boss fight. And even after that, the Blend Eye itself doesn't pull any punches, meaning you need to be careful to survive the encounter against it to avoid being ejected out of the level. It's even worse in Encore mode, where the cave with the switches [[BlacoutBasement is dark]] and the Mean Blend Eye is more agressive.]]

* AuthorsSavingThrow: Version 2.1 entire reason of existing is this, as it fixes several of the most common complaints players had with this game such as giving more oppoturnities to skip the ForcedTutorial, making features like Online play, Addons and Time attack quicker to unlock and nerfing the RubberbandAI.

* HilariousInHindsight:
** This game was in development long before the announcement of an official [[VideoGame/TeamSonicRacing Sonic-Universe racing game]].
** Additionally, the game was released at least a good full week before ''VideoGame/CrashTeamRacingNitroFueled'' was announced at the Video Game Awards 2018.

* SurpriseDifficulty: Record Attack might seem simple, but some of the silver medals can be pretty tough to earn. And then you usually have to shave about another 20 seconds for the gold medal.

* ArcFatigue: ''Ring Racers''[='=] ForcedTutorial on release was slammed by many people online for being needlessly long, clocking in at around 40 minutes ''at least''. This wouldn't be as much of an issue if it didn't waste the players' time by recapping basic mechanics already known from other racers including ''[=SRB2K=]'' as well as talking about niche mechanics that are heavily situational at best, and the fact that you are required to do this to access the main game doesn't help matters. There ''is'' a way to skip the tutorial, but it requires [[GuideDangIt doubling back into a tunnel behind you]] and completing a race with hard [=CPUs=] at 4th place or higher, or being able to put in [[spoiler:gaster]] as a password. Thankfully, the very first patch only made the first level of the tutorial mandatory, but also made the tutorial challenge race more visible at every step of the tutorial, as well as made the actual challenge much more in line with normal difficulty, and completing it unlocks online play, addons and time attack all in one go, while also making it easier to add in the password to skip the tutorial.

** Among those achievements are obtaining the Chaos and Super Emeralds, which can only be obtained from the Sealed Star Zones from the first 14 cups. But to even get the chance to get to a Sealed Star Zone, it is required to complete a specific GP with enough points from Rings, Lap Bonuses, Egg Prisons, GP Points and the final GP placement, while also not using too many continues - and then however many continues you have left is the number of chances you have to get the Emerald. Run out of chances during the Sealed Star stage, and you have to start all over again from the beginning of the GP just for another chance at the Emerald. You also can't access the Sealed Star Zones on the Easy difficulty. Almost as if to rub salt in the wound, there's also a challenge to obtain all 14 emeralds '''AGAIN''' on the highest difficulty.

** The shrines from VideoGame/SonicAdventure2 appear hidden on certain stages and each one will unlock a character or follower. They can be really well hidden already but it's not enough to simply find them. Just as they originally did, they require the Mystic Melody to be played next to them before they'll activate. How do you get it? [[spoiler:Find it on a track... in the Egg Cup. The **14th** cup in the game]]. The game neither tells you that the Mystic Melody exists, how to obtain it beyond "find a secret", nor how to even use it once you DO obtain it.

** Flame Cup has three [[SlippySlideyIceWorld snow and ice tracks]] one after the other, and if the game was tough but fair before, it becomes vicious with these three tracks:
*** First, Diamond Dust starts on a slide where you must be frozen in ice at least once, and the second half of the track is a long ascent to the finish line. However, the electric barriers and the bumpers coupled with the ice physics mae it way harder on practice.
*** Second, Blue Mountain Act 1, [[AbridgedArenaArray one of the favorite of the community]], is way less fun in a Grand Prix setting. The track has three caverns where you must roll on ice, the third being the most tedious as it forces you to zigzag between barriers. Also, while the slippery physics are troublesome for the player, the CPU will abuse these to go even faster, and even worse, the game often tends to give them an unlimited amount of rings. Also, while you can destroy fir trees while invincible or giant, snowmen can knock you down if you roll on them.
*** Third, Blue Mountain Act 2 is even worse, as it is not a three lap turn, but the equivalent of [[VideoGame/MarioKart8 Merry Mountain and Mount Wario]] combined, as you have to ascend a mountain before descending to the other side. The second third of the track may be the worst, as you have to ascend while crossing huge gaps at top speed to not fall down. This track also has the ridiculously tough snowmen.

** Balloon Park features a sharp turn into a pair of moving walls with a small gap in the middle. It is one of the most annoying and chaotic parts of the game. And this track has five laps. ''Of course'' it has five laps...
