I have no idea what they are

I only have one Switch and have no plans to get a Switch 2 so they don't really make any difference to me, but they're certainly confusing. I don't know why they decided to make digital games more complicated.

ehhh cool in theory but valve does game sharing better

Virtual Game cards are pretty confusing, and their usefulness is too situational for me to think they are useful.

I think that virtual game cards are a scam, but the worst thing is that the Switch 2 cartidges will just exist as some phisical download code… So they're completely useless. Another thing that annoys me are the games' prices (80$ for Mario Kart is a scam)
