These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Shining Force
Anticlimax Boss: Darksol in the first game - Despite being the Big Bad behind reviving Dark Dragon and the boss of the penultimate battle of the game, he is incredibly weak compared to your party at that point and his only special ability is no real danger to anybody.
Character Tiers: To list the examples would take ages. Teel;deer version: There's a buttload of differences per each game. Even worse is when there's Tiers within the own classes. (This is due to Loads and Loads of Characters, of course.)
Cliché Storm: Most notable in Shining Force II, somewhat less so in the original.
Zylo from the first game and Slade from the second are both well-liked.
Even Better Sequel: The first game was certainly a very good game in it's own right, but there are few who would tell you that the second didn't take every single aspect that made it good and polished it to a shine. (Including balance issues!)
Goddamned Bats: Bat creatures, almost exclusively appearing in the earlier stages of the games, can avoid all obstacles and barriers, and have a good chance of putting a character to sleep with any attack. There is no way to cure Sleep, aside from waiting several rounds for it to randomly wear off.
Mary Sue: Arguably Narsha in Resurrection of Dark Dragon. She is Ramladu's daughter, who takes it upon herself to save Runefaust from her now-Brainwashed and Crazy father. She also uses a powerful weapon and owns some of the best healing spells in the game. Though in a game with relatively little character development (not surprising given Camelot's other popular series), it's hard to concretely pin her as such.
Particularly vexing to some is that she replaces Mae as Max's love interest in the remake, even stealing some of her lines at the end of the game (while Mae isn't even present during the scene). Narsha being compared to someone's shoehorned OC in a fan fic is almost valid.
Rescued from the Scrappy Heap: The archer class began as nearly useless in Shining Force I, becoming moderately useful with their new-found advantage against flying foes in II, and invaluable team members with improved stats and useful special attacks in III.
Evasion rates in earlier titles, especially the first game.
Seinfeld Is Unfunny: It can be hard to appreciate the series, especially the Genesis-CD-Game Gear-Saturn titles after having been spoiled by later Fire Emblem games and more in-depth Turn-Based Strategy games. The first story had several clichés for the day; but right now it looks like a Category 5 Cliché Storm.
The first game also has plenty of balance issues, too. The remake also received some criticisms for many tropes it helped create alongside Fire Emblem.
Also, after playing Shining Force CD and Shining Force II, it can be hard to go back to playing the first one again.
Tear Jerker: Kane's death in the first Shining Force game, Oddler/Oddeye's death in the second.
That One Boss: The Chess fight in SFII can be incredibly difficult, in fact it's one of the most difficult bosses in the game, and it's not even at the end but towards the middle of the game.
Marionette in original Shining Force, which is also an Early Bird Boss - he has infinite MP and can cast Freeze Lv. 3 in a huge radius (which is basically an One-Hit Kill for one to five of your units on this point of the game), and his health is always regenerating, all of which makes him insanely hard to defeat even for a skilled Tactical-RPG player.
Iom, from Shining Force Gaiden II: Sword of Hayja. Yes he's a Final Boss, but he has to be one of the hardest final bosses in the series. Dark Dragon and Zeon really have nothing on him. First off you have to contend with overpowered Mooks attacking you while you try to fight the insanely over-powered Iom, who not only are powerful enough to be bosses themselves (from the previous couple of battles at least) but infinitely regenerate after you defeat themnote There's a trick though. Place a character over the space where the mooks regenerate and they can't come back anymore.. Then there's Iom himself, who is invincible until attacked with the Sword of Hayja, and even after that his HP is about 300. His 'demon breath' will easily cost your character 30 HP (and by then most of your best characters will have between 40 and 50 HP), and he's quick enough to be able to do it twice in a row before your character has the chance to heal.
For a fun boss fight, you need only RELEASE THE KRAKEN. From Shining Force 2. The first point against having a smooth fight against this boss is that, due to semi-poor game design, most rookies blunder into this fight before a couple of other battles that, by levels, should come first. As such, they go in rather under-leveled because the game has little indication of where you need to be going at this point. Number 2, every monster in the fight is unique, and newly introduced monsters tend to pound on you harder than they ever will again because they'll be of a higher level than you are meant to be anyway. Third, the map is mainly impassable water with little in the way of room to maneuver for you. There's no circling your enemies. Once you get into the fight, you're fending off the legs, holding your own, in come the two arms with their increased range and an AI that will almost always take the One Hit KO. Healers and mages are often in this category. And you get through all that? In comes the Kraken Head, the first creature you fight in the game that has a 3-tile attack range. There's pretty much nowhere on the map you're safe from it unless you've killed all the legs & arms on the opposite side of the boat. And all this is pretty much happening on a turn counter, you don't really have any control over when the head, arms, or legs strike except by moving someone into range to speed up the process. And this fight occurs fairly early in the game, maybe about 1/3 of the way. You don't have a big enough group to organize your own team, so it's just who you've got at the time.
Peter, Game Breaker that he is, does help mitigate some of the Kraken woes a bit, as he can fly, he hits like a truck and he revives himself after each attempt, but that's not saying a whole lot...
