Forza Horizon 6 is going to be bonkers massive, it's already a tens of million franchise per entry between only Xbox and PC. Forza Horizon 5 reaching 50m+ players lifetime, including millions sold individually on Xbox and Steam. Millions sold on PlayStation despite being a 4 year old port. Game Pass has grown since 2021. The franchise has exploded and it will now launch day one on PlayStation 5. Xbox established player-base (millions) + Steam (millions) + PlayStation 5 at launch (now millions fanbase) + Japan (easy hype driver) + 5 years since the last entry. I think outside of Mario Kart it will be the biggest racing title launch ever in sales alone, that's before we even get into players, Lol.
Forza Horizon 5 had over 1.2m premium edition buyers alone, the more expensive early access option which was an estimate of $54m-$118m in revenue before it even released fully to everyone. It reached 4.5m players less than 24 hours after launch and over 10 million in the first week. So what do we think Forza Horizon 6's early access premium edition will do (if they still have a leaderboard to check, Lol) now that the player base has expanded and it has added PlayStation at launch. What do we think it will reach 24 hours after release and 1 week after released?
Servers are going to die.
Also that isn't even counting that there's a possibility of it launching on Switch 2 but I wouldn't say that's a sure thing.
