Japan typically accounts for 75% of Dragon Quest sales, maybe more. I made a thread a couple days ago about how DQXI on Switch (from my perspective in the US) seems to be getting a lot of good marketing from Nintendo, and it's been near the top of the eShop charts, etcetera. Someone even mentioned how it might do better on Switch than it did on PS4. If trends follow, then sales in the US would be around 50k ~ 60k (just a rough estimate).

Dragon Quest is insanely huge in Japan. Extremely popular.

No, we don't know sales numbers yet for the US, but given how much buzz the game is getting here, I was anticipating bigger numbers from the land where Dragon Quest is a household name.

Also, I don't think it's fair to say that it's a port, given that the game was planned to release on PS4, Switch, and 3DS (IIRC) early on, and yet the version that ultimately did get released on Switch is not the same game anymore.

So yeah, I'm not a sales expert, but I can say that the numbers I was expecting to see were more than 300k. I don't think 300k is abysmal, though. Maybe not even terrible. But do you really think 300k is "super well"? Not just "regular well"? Or are you exaggerating it's "well-ness" to make a point about how much you disagree with it doing "un-well"? Welp, does that make sense?

(Sorry for the above, just my dumb sense of humor. :P)

No I think it is super well lol. Even though it is a definitive edition, a port is a port. I also don't think for a second that 50-60k in the US is completely accurate for a estimate. My reason for this(which might be 100% off) is that DQ in japan is treated as such a main event, that everyone played in and was well aware of it. DQ11 in the US last year...really didn't have that same effect. It was overshadowed and I can't even remember where it was showed off at besides in Sony's e3 presentation. With how much of a big deal Nintendo has made this game, I think that percentage won't hold true. So yeah, I think it did really well, and I hope Square is happy with it because I really don't want to wait 2-3 years for DQ12 lol

It actually did very well last year in the US compared to previous installments.

"According to the NPD’s Mat Piscatella, Dragon Quest XI‘s launch sales have been the greatest in franchise history, which dates all the way back to Dragon Warrior on the NES. Perhaps more impressive, and maybe even surprising, is that he says the launch sales were more than double those of Dragon Quest IX‘s, which was not only the last core entry of the series to release in North America, but it was also published by Nintendo.
Dragon Quest XI certainly got quite a push this year from Square Enix, but many were worried the game would underperform due to its release timing, mere days before the record-obliterating Marvel’s Spider-Man. While Dragon Quest XI is admittedly more of a niche title in the west, it seems like the extra juice is paying off, at least for the launch period."

Also, it even charted at number 2 in it's launch week in the UK behind Spiderman. Plus keep in mind it did launch for PC in the west and steam spy has it currently between 200k-500k owners. A lot of people would have picked up these versions over the last year for cheap and only the hard core Switch fans will likely pick this up. I highly doubt the Switch version will outsell the PS4 one, especially with LM3 and Pokémon launching in the next month and 6 weeks respectively. Switch owners will have likely moved on at that point anyways. 

I’m on mobile right now, so I can’t get the link, but after two months DQ11 outside of Japan shipped+ digital was like 400k lol. I’m sure it crawled it’s way to 500 or 600k, but IX ended with over a million outside of Japan 

600k actually. They shipped 3.4M on 3ds and PS4 at that time and 600k for the West was announced after 2 months in Nov 2018. The 1M+ for IX shows on this site but this site no longer tracks software sales directly as they admitted they were unreliable. Plus, it's almost been a year and the game has been on flash sales on PSN and Steam a number of times. Hell even retail stores like Best Buy and Walmart plus online sites like amazon has had it for $29.99 and lower at times over the year. SE got a huge bump in revenue with the initial $60 price tag in the US and likely got a ton of cheap buys since then. It will definitely crawl over a million here or already has. My point still stands. I hope you enjoy it regardless. I paid 90+ dollars for it in Canada and plated the game.
