Perhaps Mario, would be able to explain why some features, as above are left out - certainly with these in RC2 would literally have been the rugby game of our dreams. Is budget the answer?
A lot of it just comes down to complexity. Rugby is complex in that at any given time the ball carrier can run, pass, or kick in any direction, while the large numbers of players on both sides need to react to that moment to moment, through the lens of the rules of rugby, moment to moment tactics, and higher level strategy. Sprinkle on top of that a lot of "odd" formations and physical situations requiring close proximity or contact, which is both formal and freeform. When you translate that to game form, that complexity manifests in terms of big challenges in animations, pathfinding, controls, AI, physics, game management etc.
In other words, making a rugby game is hard, and like any game development you are going to be constrained by the limitations of talent, budget, and time. So you have to pick your battles. And sometimes that means leaving out whole aspects of the sport in order to devote more time and effort to those things you
have included. The alternative is a sprawling game that includes "everything" but probably does most things poorly.
Now, you try your best to leave out the more obscure or more advanced aspects, or things which just aren't "bang for buck", and include and focus on the things you deem important. Not everybody is going to agree, not even internally, but the choices have to be made. And you have to make those choices from generation to generation of the game. Again, not everybody might again you are working on the right things.
And to some degree, some people will
never be satisfied. When emulating any real world sport, there is
always more depth, complexity, and nuance that sport fans want to see reflected in the game e.g. "socks". Even if you make all the right choices, and do an amazing job to a high quality, spending your budget in the most efficient way, there is
always something else that could have been added. Even well funded franchises like FIFA and Madden face this never ending treadmill.
In any case, that is the vague answer to the question of "Why didn't you have X in the game?" that might apply to us, HB Studios, or any other sports game maker.
Hope that helps shed some light on the "problem" even if it doesn't speak to our specifics.
