The PS4 launched at, like, 2000-2300US$(4000RS$ at the time), but even the Megadrive is still expensive 300-400RS$(160-220US$ at the time,90-130US$ nowdays).

From what I remember here in VGC was that until the release of PS1 the Mega Drive/Genesis was ahead of Super Nintendo.

On Sega saying they sold over 40M, they legally can't lie about that so we have to accept the numbers.

On the shipments of famitsu. In Brazil Tec Toy manufactured Mega Drive and Gradient manufactured Snes. Don't know for sure if any of them would enter the shipment figures of the companies, but I would be positive that the famitsu figures wouldn't.

Mega Drive was selling in stores up to these days, there may be one or two years since the last time I saw a Mega Drive on a store, and there is a new Master System being sold.

About the arm and a leg, that is a little false. When I bought my PS1 it costed R$350 (equivalent to about 200 USD) in 2000, My PS2 was R$ 1000 in 2005 (equivalent to 350 USD) and unfortunately Mega Drive wasn't much cheaper, and surely both PS1 and PS2 were over 2x more expensive than in USA even on the grey shops, at the time neither were officially released by Sony in Brazil. One thing I can say for almost sure is that Mega Drive sold more in Brazil, perhaps because its games were a lot cheaper and there were some counterfeit cartridges.

Here is a link of Tectoy still selling the Mega Drive https://www.tectoy.com.br/pre-venda-mega-drive-edicao-limitada/p/995040461825 in Brazil, R$ 450 or about 120 USD.

It seems like they only got a lifetime license to manufacture the Master System and the Mega Drive, not ever getting a license for Saturn and Dreamcast unfortunatelly. I would like to have a pristine version of both.

Also because of the simplificity and some kind of "free domain" chip of NES, in Brazil there are still some companies that sell the "same" version of NES they sold 25 years ago like the Dynavision... And of course there are the rip-offs in Brazil that came with the names of Polystation (chassis looking like a PS1), Polystation 64, Polystation Wii (those are the ones I saw personally, not sure they made the PS 2, 3 or 4) this one came with the pistol and all.

According to the graph Soundwave puts up, Snes outsells Genesis in 1992, years before PS1 hits the market.  even if we were to assume the chart is biased, there's no way Nintendo passed Sega by almost 20 mln in the last year and a half of their prime.  Street Figter Ii, Mortal Kombat, Donkey Kong Country, Sonic the Hedgehog...these systems were in their prime in 1992-1995.  actually, the surpriaing thung to me is that snes sells more in 1996 than 95 according to the chart!  Maybe price drops or something, 96 was a pretty zweak year for snes.

as for the rest of your post, intersting, but who would be tracking those sales of old consoles in Brazil with any accuracy?

I remember thinking about this recently and coming across this old post on:  http://www.sega-16.com/forum/archive/index.php/t-9132.html 

Wikipedia's 29 million is wrong.

Genesis: 19 million
European Mega Drive: 9 million
Japanese Mega Drive: 3.58 million
Majesco's sales: 2 million
Nomad: 1 million
Brazil: 2 million

That's 36.58 million. But what's missing?

Australia (Ozisoft handled it)
South Korea (Samsung handled it)
India
Other Asia

So if we assume they sold 1 million in each of those regions, we have 40.58 million units sold.

This is Wikipedia's sole source for the 29 million number.
http://www.wired.com/gaming/gamingreviews/multimedia/2007/05/gallery_game_history?slide=21

It's not exactly sturdy.
We can give them a better source, with better, more accurate numbers.

That is the graphic he put, what I was saying is something I have seem here a lot of times, perhaps from out Megaman friend that loves to do graphics (always forget his name, but he post a lot of then in the NPD threads).

In Brazil we had from time to time a magazine called Veja that would track or make ranking from games... but Tectoy themselves would be a good tracking on their shipments if anyone were to get those numbers.

And this would be much closer to Sega numbers.

This is true. We call it Mega Drive in here and we even got a new re-launch this year. This new version even include SD card input:

OT: But I still think 40 million is a little exaggerated.

40 M is too high but I don't quite agree with the 29 M either.

If we break it down... this article by the NYTimes seems to suggest that by 1998 the Genesis in America sold up to 20 M, I'm not sure on the European source but I see 8 M listed often and about 3.5 M in Japan. This brings the total up to 31.5 M and once you add the rest of the Majesco sales and TecToy you'll probably end up around with 35M.

It seems unlikely that Sega sold 1M each in Australia, SK, India and Other Asia (unless if someone can provide a source?) but maybe 1M all together. Overall the SNES and Genesis were pretty neck in neck if you only count the Americas and Europe but Nintendo absolutely stomped Sega in Japan.

Sega outsold SNES from 1991 to 1994 in the US. By that year, Genesis and Sega had more marketshare than Nintendo in that territory. By the end of the year, when DKC dropped, Sega of Japan had already abandoned ship and foolishly started trying to push the Saturn because they were worried Sony and Nintendo would get the drop on them if they waited. This caused everything to collapse, along with the lead the Genesis and Sega had accomplished. We all know how the rest of the story goes.

I have some paper work from an analysis firm dealing with sales on a hard drive somewhere, and I think I remember the estimates were close to 40 million world wide with the bulk coming from the US.

Correct me if I`m wrong but is it true that the Genesis only lose to the SNES in Japan Worldwide?

I think that's correct. According to VGSales sources it did at least.
