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: Star Soldier
Game Breaker: In Vanishing Earth, the blue ship. It's the most mobile ship (good for keeping up your chain by sweeping the screen), with the longest Rolling, its main weapon has piercing lasers from Lvl 2 on, and it's 2nd Ex-Arm is a Wave Motion Gun that will leave almost every boss on the verge of death if they were at max health, or, if they were at the point their core was exposed, damage them so severely that it will kill most bosses right then and there. This greatly simplifies some of the more annoying final attacks used by bosses, particularly the last one. Its only weakpoint is how you need to keep the steamroller going by being careful to not get hit too much, as its main weapon, at levels 0 and 1, is easily the weakest of all three ships, and if you can't get more power quickly, you can easily lose more lives before getting the chance to recover, potentially getting a Game Over. The solution is easy: destroy anything that appears on the screen as soon as it does. With the power of the ship's lasers at level 2 and 3, this is easier than it sounds.
It's Short, so It Sucks : A common complaint about Star Soldier R, as it's strictly a Caravan game and lacks a full campaign mode.
