I like to look at the slight differences between these three phrases:
"We're making the game we always wanted to make"
"We're making the best game in ____ franchise"
"We're making the best game we've ever made"
The first one is a passion project where they expect people to either love it, like it, or hate it.
The second is where they are committed to making a game that you can look back at a franchise and say 'This was the best one'.
However, the last one...the last one means you're aiming for the coveted list of all lists.
