I'm very curious to know the answer because it will be close, I'm sure, with both games having giant worldwide appeal. I also think it's a fun comparison because both games have wildly different art styles. I also picture cloud and villager fighting in Smash Bros, and it makes me chuckle.
Both will easily cruise to the 10million line if you ask me.
My feeling is FF7R might edge it out in the long run with Xbox, PC, PS5, and maybe Switch Pro ports. But in the short term, especially due to Japan and those evergreen legs, Animal Crossing will probably do better. It's very hard to tell.
What do you think? Please share your thoughts.
Edit - I find these comparisons fun and it's a neat way to spurn conversation about the sales potential of two juggernauts. I hope you guys enjoy it too. I feel like ERA is mature enough to avoid console wars.
