One of the little things that Nintendo does that the community is fond of is how their quarterly reports update their best selling games list. While this is usually only a few games it is a nice update to see how the games are doing over time and is often accompanied by additional totals for new games or those that did unexpectedly well. 

Sony and Microsoft don't seem to do that...and it feels weird to say the phrase 'Nintendo is more transparent about their X than Sony and Microsoft'.

Microsoft and Sony regularly give away their 1st party titles as part of Xbox Live Gold or PS Plus subscriptions. Also they give access to many of their games through Game Pass and PS Now. Sales figures would be tricky to report or an inaccurate representation of how much the game has earned or been played.

Sony usually lists milesstones like 10 million copies sold. Either that or they make the information available somehow. MS on the other than hides their pitiful sales numbers behind excuses like "But too many people play it on gamepass", or "Lifetime total sales don't matter anymore! It's playercount that matters!"

It’s simple logic that if you going to aggressively push a subscription service then using purchases suddenly makes no sense. Engagement and monthly active players is actually a much better way to gauge popularity.

The income is steady and monthly. And optional purchases like cosmetic mtx for say Sea of Thieves is where the long term money comes from when you maintain high engagement and monthly active users. 

It’s a culture shift from what you are used to. Try to understand it instead of being hostile towards it. 

Individual SW sales of each game isn't that important to Sony's bottom line, so they feel that investors don't really need/care to know about it. Of course Sony will still do PR after a successful launch, touting numbers for a brief rally, but afterwards it isn't so important.

Especially when a game like GTA V makes Sony more money than almost all of their smaller games.

For Nintendo showcase sales of their IPs proves how strong is their game input and how well they keep selling over time

Sony IPs have very good launches, but not exactly big legs. For them makes more sense to update numbers when the game reaches some milestone

About Xbox I guess it just has nothing much to update, fewer exclusives and overall lower sales

It's easy to pump up monthly active player numbers when a game is free or tied to a subscription service. Just look at Poke'mon Go, with its 1 billion downloads. Now, does that suddenly mean that Poke'mon Go is the best Poke'mon game? Hell no! In fact, Poke'mon Go is a barebones shell of the original games. You'd have a hard time finding anybody listing Poke'mon Go as their favorite Poke'mon game.

Also, keep in mind that how long people play a game is in no way tied to its greatness. A game can sell 10+ million copies and be just a 10 hour single player game. Using monthly active player lists you'd think a game like that isn't very good. On the flipside a game that is manipulative, grindy, and addictive can have a massive playerbase despite being an awful game. All fun games are addictive, but not all addictive games are fun.

What MS really needs to do is man up, release actual sales numbers, and then project how many sales were lost to Gamepass. That would be more honest than what they are doing now. I get it. Gamepass costs them sales. But we are all smart people here. We can all see that if a game sold 7 million copies, lifetime, while launching day 1 on Gamepass, then that is a really damned good sales figure.

As others already said, Sony usually reports only big milestones like 5m or 10m copies sold for their games. MS on the other hand uses strange metrics like how many jumps have been made or how many shots fired in game X, which is very confusing and doesn't tell anything about a certain game's performance at all.

On topic, companies releasing numbers for their games isn’t required on a quarterly statement. It’s better off being told to us via tweets. It’s for gamers who are invested, not for investors.

Like the fiscal quarter that covered August MS said that 1st party was driving a lot of engagement and revenue. That’s covering the 4 games Tell Me Why, Flight Sim, Wasteland 3, and Battletoads. That’s all we really need to know. The stats that Flight Sim sold over 1 million on Steam and played by total 2 million players is a nice bonus. 

But regardless it’s no longer a good metric to list sold when you pushing GP. Seems your criteria is solely meant for PS fans to dissect and use as ammo against Xbox fans online. To MS, they don’t care about “losing sales to Game Pass” they care that you play their games as much as possible. The revenue comes in other ways rather then just upfront like you are used to. 

I like hard data, so I like Nintendo's way of doing it. Since Microsoft almost doesn't provide any numbers I stopped caring.

Sony games usually don't have very long legs, so providing quarterly updates wouldn't be to interesting, but yearly updates would be something.
