To solve A and D, I think the app probably should not contain the story games, that means that it would not be nearly as much data. This also solves the problem of people having already paid for the story ones.
The story games already exist on some app stores so this multi app could just contain links to them in the app stores.
To explain C. The point I was trying to make earlier is that having less apps on the App Store costs less so having a master app would save money.
And B, the only game that would be left on would be BB blast and rainbow
These are quite simple games so the combining them would be easier than in the suggestion before.
So basically it would be just a complex version of BB backpack lol.
So Features could Include
-Top BB yt channel and vids links
-Links to forum
-Links to Wiki
-Links to SkyVu and BB website
-Links to all BB social media
-Links to BB storyline and Multiplayer in the App Store
Basically all seems a bit pointless now, the only benefit is that it saves money instead of releasing old BB games separately
The price to change name is needed on BBO it avoids trolling, on BBG there is no chat so this is no problem.
The name change exists to stop people impersonating each other, spamming each other with name changes. It also means that there can be only one use of each name.
