But they're worth 20 usd on other consoles. And keep in mind, that by conversion, Europe is already more expensive than US so 20% isn't really that much. I do take advantage of the eshop though. I buy from US and the state I chose has no added tax. In canada there is a universal 5% gst but also added qst so I chose a province with none of that. I buy from japan sometimes because they can be cheaper. All in all, I try my best to get these sorts of games but this small reduction isn't in my budget. For ninty games, I know they won't reduce in price even if wait a decade, so I just buy the ones I really like for full price like BoTW, splatton 2, XC2 and now smash. But even for first party, The games that I want but not the top of the list, like pokemon, mario odyssey, mario tennis, mario party, mario kart, donkey kong, etc etc etc I don't buy becuase I can't afford. And when I can afford, a new game that really catches my eye like megaman 11 or smash or maybe even metroid next year or the daemon x machina game comes along and I have to leave these games behind. For wii u, i just bought the third party ones when they dropped to 20. That way I gathered cash and could get 3 games. With switch though discounts are much rarer and less valuable
There was a fairly decent first party sale a while back, think it might have been on the one year anniversary of the system but mk8d and splatoon2 were definitely reduced.
As for games costing different amounts on other consoles, cool, keep in mind how in some cases you are talking about games which have been on those other consoles for an extra year it more, Doom didn't launch PS4 @ 20 and if you wanna be thrifty with things like the stock of Truth for example you could but an xboX 360 and copy of that game used for around 50e, won't have it portable or on your new device, but that's the cost associated with those things over years old version.
