The one and only time I “cheated” at Elden Ring was to spawn in some DLC weapons (hand-to-hand arts and perfume bottles) for a brand new character. Not because they were overpowered but because I hadn’t used them on any of my previous characters and they looked fun so I wanted to use them for a full playthrough. And they were quite fun. Better than I expected too, but certainly not top tier weapons.
Of course I could have just asked a friend to drop them for me instead but it was easier to just “cheat” them in :)
When you plug Sonic 3 into Sonic & Knuckles, that’s what Sonic 3 was intended to be. But they couldn’t finish it in time, so they split them into separate games. That’s why when you play Sonic 3 & Knuckles, you don’t just play Sonic 3 as Knuckles, you play through both Sonic 3 and Sonic & Knuckles (as opposed to Sonic 2 where you only play through Sonic 2 levels as Knuckles).
