But the difference is not 4-5€, it's 10€. If what you said was the case, are NS cartridges that different from DS/3DS ones? Those managed to keep their prices around 40-45€, and Nintendo still was the only one manufacturing DS/3DS cartridges.

On the Vita I don't want cartridges anyway. It's got one cartridge slot and I don't like to carry additional carts so I make a choice which cartridge game I want to play that day and install that and then have a wider selection of small vita games on my 16GB card. Typically I use the cartridge slot for the largest games and choose to buy large games on cartridge. This balances the limited storage well. For example on Switch I would not want Bomberman as a cartridge. I'd want Zelda as the cartridge and smaller games on sdcard. Also with Switch game pricing being so high and storage being relatively cheap its not the same as Vita but there are some parallels. Also because of Switch pricing and poor account flexibility I'd want most games on physical for resell value so this would limit me probably to only the big exclusive Nintendo titles. I think its going to be very difficult to build up a reasonable library of Switch games at a competitive price. If you buy 4 small games at £50 each as digital that is the cost of a ps4 or xbox one. Every game would have to offer 10's of hours of fantastic content to justify those prices and not be available on other formats. For me only Zelda offers that currently.

You've got to be kidding me. The amount of work put into games these days. Games are much cheaper to buy than they used to be.

I just ordered the cartridges of "Steins;Gate Zero" and "Root Letter" for £17 (~ €20) each, the PS4 versions on Blu-rays are still higher priced:

• https://www.idealo.co.uk/mscat.html?q=steins+gate+zero

I'm sure that supply and demand are much more important for the price setting (and later price reductions) than the production costs.

Due to the sparse selection so far, there is a high demand for new Switch titles and publishers are trying to take advantage of that. If many of the Switch buyers let them get away with the price increase, it won't change and Switch versions of multiplatform games will stay more expensive than the other versions.

For a second I thought those were Switch games. Vita is pretty much dead with some serious discounting. If Vita had sold 150 million with people rushing to buy every new game we would see games close to suggested retail price. Sadly Vita games won't sell now without heavy discounting it seems.

Except that "the inflation nonsense" is also what steadily increases your wage. Things are getting more expensive but money to spend increases as well. That's why it's true that game costs do not increase. Wanting things to stay at the same price for years is wanting things to become cheaper.

Typical practices especially nintendo

Um, this is seriously Kellyanne Conway level of alternative facts. The value of money changes with time. This is a fact. You can't just ignore facts here. It is like saying, "Sure it may be cheaper if you use that "exchange rate" nonsene, but I don't" when referring to euros and dollars. A 2017 dollar has less value than a 1985 dollar, because the supply of dollars is greater than it was in 1985. Likewise, for any other fiat currency. 

I think I remember buying FF9 for £35-40 back when it came out, I'm buying ME:A in week for £39... if only house prices stayed as they were is 2001. 20 years of development and games still cost the same. Dev teams have 5 times more people, costs are 5 times higher, RRP the same.

Games are cheap now. But like Ka-pi, I also never spend £50 on a new game, based on UK competition, you can find games cheaper and some lose value in weeks, let alone months. 

A 15% increase in 0 is 0 + (1.15x0)= 0. You be grateful for your increase. XD
