I dont think you put much thought into this part.

Switch had only sold 16.66 million (this sites numbers) when Mario Kart reached the 1 year mark, it would need a ~90% attach ratio.

Pokemon Gen 8 will launch in Q4 2019 so by March 31, 2020 (3-5 months later) Switch sales will be around 50 million. That would be a 30% attack ratio.

Pokemon Sun/Moon shipped 14.69 million in 1.5 months, why is 15 million sold in 3-5 months so crazy?

Okay then I am stand corrected about pokemon and also  Pokemon will not have great legs then if that is the case. 

 Anyway it’s still doesn’t disprove my point with him though but thanks for the correction though.

When i compare Nintendo and Sony games in my mind i'm doing it with these conditions:

- Games that are currently or have potential to be 10m+ sellers

- The game could be from years ago and from a previous platform but it has a version in a current platform that sold similarly or better than in the previous one, so they combine sales (Mario Kart 8 or TLOU as examples)

- I will put the lifetime sales i think the game will reach, but is just an aproximation, nothing really specific.

- If any game gets seriously bundled, inmediately this projection doesn't work.

- The game has to be already announced at least.

That said, with these conditions the games that i think for each company are:

NINTENDO:

Mario Kart 8                 25m

Mario Odyssey            20m

BOTW                           15m

Pokemon Let's Go      10m

Pokemon 2019           20m

Smash Bros Ultimate 20m 

Splatoon 2                   10m

-----------------------------------

TOTAL                         120m  

(I've put my most optimtistic predictions for each game)

SONY:

The Last of Us               20m

Uncharted 4                  15m

Horizon Zero Dawn      10m

Gran Turismo Sport      10m

God of War (2018)       15m

Spiderman                     15m

Ghosts of Tsushima      10m

The Last of Us Part II    15m

------------------------------------

TOTAL                              110m    

As everyone can see, the total sales of those specific games in my own arbitrary rules are very close for each company. That's why i think Sony is entering "Nintendo levels". All of those Nintendo games could explode and sell even more or Nintendo announce some new big game suddenly to add to that list, and some Sony games disappoint and be less. Everything i say about both companies is just my opinion, but i thought this was the best way to express what i was trying to explain to people in this thread. If i forgot a game from each one or i'm being completely under/overvaluing a game i'm open to accept other opinions.

PD: Sorry in advance fot the long post

We'll see.  Your projections for these Sony games are more optimistic than mine.  If Sony can actually get one game above 15m, then their first party will definitely be better than PS2.  And if they get more than one game above 15m by the very end of PS4's life, then they at that point they really are close to "Ninty level".  I am not convinced they will sell that much.

But I thought once they can get a title to reach 15M that's okay but now you have to include 1 more? Are we moving the goal post?
As I have mentioned GOW already sold 5M in just one month and that is not shipped. If they are talking about shipped then it could be more.

UK chart week 32.
https://www.resetera.com/threads/pal-charts-week-32-2018.62008/
It's number 7 at all formats and no. 2 at single format.

Germany at 12 on all formats for July and no. 2 for June.

NPD May #2 for GOW

June NPD #2 for GOW again.

So if they can reqach 10M-12M on 1 year annivof GOW and then we add more 2-3 Years GOW won't reach it?

Now let's talk about the other 3. All those numbers are not shipped so it's not blind optimism but rather expectations in line with the sales trend. I already provided numbers. You look it up and do some analysis before your pessimism on the games I mentioned. 

Once again you missed the whole point of the thread. You are still hung up with the phrase "Ninty level" If we compare Sony directly to Nintendo's overall output then Ninty without question is number one.

I updated the thread with Spiderman

3.3M in 3 days. Wowzer!

Lol at the ninty fans that cant accept sony is reaching nintendo sales levels. Without milking the same franchises for 30years.

I'm also stand with Pokemon.

They earn it years and years of work from Playstation

Very good predictions...., but I feel that Splatoon 2 won't reach 10M, is around 6'5M right now, to sell 4M more is a lot....The one i think it will surpass the 10M is Pokemon let's Go, don't ever understimate Pokemon. 

And for PS4, don't forget about Days Gone. Lot of people are understimating the success of open world/cinematic/polished/zombie games. Days Gone will be closer to 10M than sell less than 5M in my opinion. I expect Ghosts of Tsushima to do a lot better than 5M too, open world/historical/polished games just sell a lot, and by the time it launches the hype for the game will be big.
