## Product: Nintendo Switch 2 Console

**Game Key Cards** are a new type of game cartridge for the [Nintendo Switch 2](https://shopsavvy.com/products/c86770d3-9657-f2ee-cb8a-367a55249b4b) that contain only a download license—not the actual game data.

## How Game Key Cards Work

1. Insert the Game Key Card into your Switch 2
2. The console downloads the full game from the Nintendo eShop
3. The card acts as license verification—you need it inserted to play
4. Game data is stored on internal storage or microSD Express card

## Why Game Key Cards Are Controversial

| Concern | Impact |
|---------|--------|
| Requires internet | Can't play until download completes |
| Storage space needed | Must have room for full game download |
| No instant play | Loses main benefit of physical media |
| Resale questions | Essentially a download code in cartridge form |
| Same price | Costs as much as traditional cartridges |

Many players feel Game Key Cards eliminate the advantages of buying physical games while keeping the same price point.

## Which Games Use Them?

Not all Switch 2 physical games are Game Key Cards. Larger titles that won't fit on standard cartridge sizes may use this format. **Always check the packaging before purchasing** if this matters to you.

## Traditional Cartridges Still Exist

| Format | Plays Offline? | Full Game on Cart? |
|--------|----------------|-------------------|
| Traditional Cartridge | ✓ Yes | ✓ Yes |
| Game Key Card | ✗ Initial download required | ✗ No (license only) |

Many Switch 2 games still come on traditional game cartridges that play directly without downloading. If you prefer physical media that works offline, look for games explicitly sold as traditional cartridges.
