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: Radiant Silvergun
Big Lipped Alligator Moment: Because the arcade version leaves out most in-game dialogue and cutscenes from the Saturn version, a number of these moments happen for arcade-specific players.
For example, when fighting against GEDO-O, everything turns into a pseudo-Retraux-style wireframes complete with beeps. In the Saturn version, a small in-game cutscene occurs just beforehand where Tengai orders Creator to analyze and record your fight with the GEDO-O. The change to wireframe is concurrent with the start of the recording.
Breather Boss: Nasu is relatively easy boss after Golets and before the dodecagon which transforms into a cross.
That One Level: For those who want to get large chains, 5A is probably the most challenging one and it takes place during the boss fight. There are tons of drone ships flying around and the second phase of the fight has kamikaze ships flying at you, wall turrets firing at you and at the same time, walls like to periodically close in with a huge missile flying through, girders slide through the corridor and eventually the whole boss starts rotating. Hit a wrong enemy and the chain is reset.
