The first time I played SG, it was Ch 4 (that too with full ctrl). And play correctly starting ch 4.5 (forget beta or full version). I played as many paths as I could choose from, so it's safe to say I looked at all the scene the game provided.
And I started collecting all the final/full versions that had been released, and played them all (with ctrl of course) to see the differences between all the available versions, but I didn't play all the paths.
Recently I played ch 3 and 3.5, and then ch 4. I discovered there was a scene I missed
![Roll eyes :rolleyes: :rolleyes:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
, it happened in ch 3 and 3.5, and was removed in ch 4.
If you follow Bella's path (go to Mario's house), you will get this scene.
If you follow Nami's path (stay at home), you will find this scene, and the deleted scene in ch 4.
