I think Nintendo should wait just a few more years and then buy some Western companies. If nothing else the dollar keeps gettin weaker relative to the yen. This keeps hurting Nintendo (and Sony) when they sell products in the US and then convert the money to yen. However, it becomes a benefit when Nintendo is buying, like buying a big Western company. They basically get it on sale. Also Nintendo is sitting on a huge mountain of cash that only seems to be growing.
I think a really good buy for them would be EA in the 2023-2025 time period. Nintendo systems lack big sports titles, so they would benefit a lot from having Madden and FIFA as exclusives.
FIFA isn't allowed to be exclusive afaik and EA's market cap is ~$40bn.
Don't Play Stationary 4 ever. Switch!
