My two cents would, if at all possible, start at an even lower domestic competition and work your way up, without necessarily staying within your country of birth. For example, fill in an application stating name, age, country, etc and start with say the Southland Stags in the ITM Cup and work you're way up to the next job. Depending on your performance with your local team, which can last one to three or whatever season, other jobs will then open up. So maybe go coach an English Championship side before going up to a Magners League side. When you get to a certain level in your career then you can apply or get offered other jobs such as the Barbarian job, then work into an international job scene, say Japan before the winning goal of the game; coaching your country of birth, unless you are from Spain then one of the big 10. Coach your team to the world cup or a lion's tour.
Don't restrict the game to this world cup, we have England in 2015 and Japan in 2019 so make a person work for their career.
This could work for most rugby playing nations, if again licences were available, say in Ireland or Wales just start from the AIB or Welsh Primer ship.
With this season mode I feel that every aspect of coaching a real team should be put in place, from sorting out training and focusing on certain type of game play to hiring and firing of players which are effected by form, injury and international call ups. Like any other sport game you will have a board of directors who expectations must be met.
Another Idea that I had and mentioned in another thread, and please give feedback, is the idea of using story lines in season mode. In different season flames of hatred are fuelled by the media and by the bad mouthing of the coach. So for example, New Zealand Australia rival. Not that it needs extra fuel but in the build up to the tri-nations Robbie Deans personality attacks you as the New Zealand coach. The game tries to build pressure on you the gamer from all angles such as media, fans, directors and so on. This could work in Europe with club sides, I mentioned this already in a other thread; after a spell in which you were the academy coach for Toulouse (where during a game you could only control your selected academy players) you move on to a new club, as head coach of say Sale, were bad press, rumours fan the flames of hatred between yourself and former club Toulouse, which ends with both teams, by no accident, meeting in the final of the Heineken Cup, thus ending the story line.
Others story lines can be such as injury crisis, star player injury, run of poor form, underdog, hated league, local or cup rivals, race to win the league, or like when they hyped up Munster first Heineken Cup by saying they have for filled their "density"
Thoughts?
