Deku Deals now lists which Nintendo Switch 2 games are on the cartridge

Literally the greatest website of all time! Heck yeah!
To get cheaper games, it’s… but physical releases covers even the most obscure games on their website.
Nintendo nearly had full advantage over all other consoles by having everything on the card without any downloads needed.. and then key cards came along to screw it up.
This absolutely 100%! They pretty much had it in the bag against all other possible purchases just by being on the Switch and Switch 2, but instead chose to drive incentives elsewhere if not destroy them altogether. Most of the games don’t even need it as they easily fit on and run off the cart and sometimes would have been better optimized had they gotten the physical treatment. Looking at Capcom titles such as Requiem, Pragmata, the smaller SE titles, P3R, and especially Pokopia.
Cool, but I don’t need this because every key card game has that awful banner I can see within a 500 mile radius of a game key card game.
But what do you prefer? That Nintendo releases cartridges with larger capacities but also much more expensive, which will affect the price, or this cheaper alternative?
Also, games are getting bigger and bigger and physical media can’t keep up, digital is the future, we have to accept it.
Besides, you complain about the gamekey cards, but I bet a lot of you buy on Steam or GOG, so stop that hypocrisy..
I don’t know, key cards are annoying but they don’t infuriate me. I think the worst part is that stupid banner on the box. But I have bought plenty of game key cards, but I prefer actual physical copies.
Actually, on GOG, you own the video games, unlike on Steam, where we mostly just own a license.
Physicalreleases.com has been doing this since Switch 2 release
walmart racks perfectly cover the banner so you cannot discern which are GKC without asking an employee, putting you into a trap where you must waste an employee’s time, which becomes a pressure point leading to a sale. i will never buy a gkc.
