I imagine Big Ant will release a FanHub at some point as it would be mutually beneficial for them and fans to work on textures etc. in advance whilst they focus on the intricacies of coding and gameplay mechanics of a rugby union game (not easy stuff). Phase play in RLL3 and RLL4 was half-decent. It was very difficult to run even a simple backline move on Rugby Challenge 3 or 4.
I wouldn't mind seeing different running styles used like Konami did with PES, and kicking styles like Rugby 06 & 08. It would make the players seem more varied e.g. Jason Robinson, Rico Gear and Israel Folau each would have obviously different running styles.
If I got this game, I can't really say I'd care too much about 2023/4 licenses because 1. The FanHub could cover that, and 2. I would probably want to make teams from the 2000s, or made up teams like the way EA Sports BIG made the SSX characters in the 2000s (or even like different characters from combat arcade games like Tekken). Making a team of different humanoid like players of different species with different strengths and weaknesses would be funny if you then played against a team like France š It would be somewhat inspired by the Swordfish Studios game in 2004 called World Championship Rugby which had one team with fictional players with unmatched stats and another team comprised entirely of Jonah Lomus šš
