For Mario Party Jamboree, and Kirby and the Forgotten Land they are including additional content (a bit like adding Bowser’s Fury or Lanky Kong). For the Zeldas they are adding second screen features.

I don’t like the up sell but it is offering something, I can see them feeling they have a justification for the fee there.

Really I’m surprised they are offering the upgrade licences as cards they can sell in 3rd party stores, hopefully we see some competition there.

Edit:

The Nintendo published games receiving free updates are listed here:

Switch titles were great because most titles I purchased were either 1st party or indie.

The Indies were usually modest in scope and priced accordingly and all of my 1st party games were purchased with 2 for au$135 vouchers.

These bought the per title price down to the equivalent of us$38 (pre tax), quite a bargain and I bought quite a few games in launch week where i would have been waiting for a sale on other platforms.

Now the voucher page is telling me:

Regarding Nintendo Switch 2 exclusive games: Please note that Nintendo Switch Game Vouchers cannot be redeemed for Nintendo Switch 2 exclusive games.

If they don’t offer an equivalent Switch 2 Voucher program I’m likely to pass on the smaller releases.
