I always thought it would do very well on PC. Really good sales!
To think, it was the best selling monster hunter when it passed 4.9m, and the best selling capcom game when it passed 7.4m. And now it's at 10.3m+ and still heading up!
Bringing Monster Hunter multi-platform is the biggest success story, with sales like that they should never go back.
I simply never understood why Japanese Devs go exclusive with their games instead of multiplate. Why is persona not on Nintendo? It would sell so much more on there. Same goes for yo Kai watch. Why didn't they release it on PS?. And there are a lot more.
There is a strong audience of JRPGs on Nintendo, PS and even PC. Even Xbox has a good JRPG fanbase. They should release on all these platforms instead of just going exclusive with one. The big JRPGs who went multiplate won big due to this like FF15 and now Monster Hunter.
Capcom would be insane to ever ditch the PS/Xbox/PC userbase for future monster hunter games, even if it's a spin off they want to bring to switch that's less ambitious so switch can handle it, it should be released on other platforms.
Time and time again, the fanbases for these games are not nearly as split as you like. Lot of these teams would rather keep the budget tight than splitting up resources. For bigger games, it makes sense since the 10-15% of additional sales you see is enough to justify the cost. However, before Persona 5, the series had never been big enough to justify multiplatform. When talking about about niche genre like JRPG, you're stating the least beneficial genre for more platforms. The examples you cite show how little the extra porting did.
Officially the ps4 and xbox version has sold a staggering 8.3m units in the 6+ months it's been out. However reports from steam suggest it had a good pc debut of over 2m sales. Monster Hunter has just entered the big leagues. I've no doubt it will hit 15m+ too.
Link to 2 million? I saw where they were able to datamine that it sold 500k in the first few days. That's a big jump to 2 million.
