Well as a long time player of rugby and rugby games on console I would say
I enjoy
* The scrums and lineouts are well made, but in saying that the lineouts you need more choices for example numbers and moves. scrums better control and moves off the scrum.
* the way you can use set plays, though you need more choices, for example have different moves off the lineout, mauls, rucks, scrums, open play so you can choose on the go, it shouldnt take so long for them to get set up and not be so slow and predictable. You also need to beable to make your own moves up in a creator
* the varied stats for players, but they need to make more of a difference, and be more subtle than being great and being crap.
*The pace of the game feels right, you can play a fast paced game or slow it down. it can actually feel alot like rugby until the problems which i will ist in my dislikes happen.
*World league, The best game mode for single player. but it needs to be fleshed out, and include the ability to have more than 1 human controlled team. better trading, training etc etc
*multiplayer the game is way more fun with 2 or more players, but it needs to be more fluid and actually beable to pass to the other human player on your own team
*The ability to make choices with penalties, free kicks etc. But it needs to be like jonah lomu rugby where you just press a corresponding button so it doesnt stop the flow of the game. and more choices for different things, like when the kick off is out on the full the 3 choices of a rekick, scrum or lineout.
I dislike and often hate
*the defence, the defence doesnt mark up correctly, leaves unrealistic gaps, ai needs to respond better, tackling needs to be automatically guided towards the player with the ball just due to the camera angle you can't judge the tackle properly, there needs to be different defensive paterns not just formations, different tackling styles whether a big hit, dive tackle, wrap up, drag down etc. and a huge concern "THERE IS ALWAYS A BLOODY FULLBACK, ITS EXTREMELY RARE FOR THERE NOT TO BE ONE", like the fullback will recieve a kick, get tackled be on the bottom of the ruck then it gets turned over and magically hes back there when u kick it immediatly
*the rules are well wrong in many instances, like throw into the lineout not straight, it isnt a penalty
*kicking needs to be more fluid quicker more different types, better bounce physics
*Rucks and mauls, rucks are just a joke, the turnovers make no sense. even the lower teams of world rugby can win the majority of rucks they have it shouldnt be an automatic turnover just cause the team isnt the best. and numbers to the ruck should actually matter. mauls should be more likes scrums with rolling mauls and actually a contest
*The AI is just poor whether the ai you are versusing or the ai on your team, it doesnt need to be fancy but itd be nice if they just played simple rugby.
