In World Rally Championship 2 you create your own rally team with a goal to get reputation and skill to make a contract with one of WRC rally teams and race in the official World Rally Championship. Best part of game is quite realistic car handling and obviously official rally teams/drivers/cars. This is not exactly a driving simulation game but is very far away from arcade racing. The difficulty settings can be adjusted to match your skill at any point of the game, which make it quite easy. Online trophies and winning every event in "The Road to WRC" can be considered as the most time consuming part of the game. The only missable trophy is "Grand Slam" requiring you to place first in every event during The Road to the WRC. Please check the trophy description for details.
There is no need to play different game modes in specific order and you probably will jump from one step to another, because it become quite repetitive to do one step at the time.
Step 1: WRC Rally School
If you are not familiar with rally games, I suggest you start with "WRC Rally School". It contains 18 quite short lessons, which will introduce you to handling of different car classes, different type of surfaces and your co-driver calls. Note: this is the only game mode where you can't use brake assistance and rewind effects. After you complete your first lesson you will get "Let it be a lesson to you!" and after mastering all 18 you get "Ace of the Race" Also you can get several miscellaneous trophies during this step. "Rolling Rolling…Rawhide", "El Mariachi", "Take it!", "Hairpin Addicted", "The best thing a man can do…", "Gravity is for Losers".
Step 2: The Road to the WRC
In this step you will spend most of the offline time playing the game and getting most of the trophies. Only missable trophy in the game is in this game mode: "Grand Slam" (see trophy description for details) Just go through all the racing programs here and win every championship/event. You don't have to win every stage or rally in championships, as long as you place first overall in the end of the championship. I recommend you select programs to race in order from 01 to 09, so it is easier to keep track of winning every event.
Step 3: Online
Online is a bit grinding for this game. And the only hard trophy is also online one. There is 10 online trophies but only two of them will take 95% of your time online. You have to get level 50 in Hall of Fame and Super Special Stage rankings. Luckily experience points you get from racing in SSS stages will increase your Hall of Fame ranking to. You should concentrate on SSS races from start. I highly recommend to find a boosting partner from this forum.
Step 4: Single Player and Hot Seat game modes, clean up.
Here comes an easy part in the road to the Platinum. You have to race few single stages in Single Player mode to get "Beat the Man to be the man!", "Historic Victory", "Know your limits… to pass them!", "Can't touch me!", "Your speed is melting the snow!", race one rally in Hot Seat mode to get "No friends in race!" and possibly get any miscellaneous trophies you may have missed earlier.
