So basically Unity game ads within Fortnite that you can buy and play within Fortnite? Curious on if you can use V-Bucks to buy these games. Though I doubt it considering they're adding their own IAP process from Unity.
Honestly it's a bit confusing on what they even mean, it's weird. It's different from Roblox from the fact that it will use a different engine. Fortnite with UEFN is already similar to Roblox except for the IAP within the games and a bit less scope capabilities. I guess we will see more in time.
At first I thought it was to allow devs of Unity to easily develop for UEFN until I watched the vid.
