I believe this helps support Ivory Tower while also giving us gamers a little break considering we have already spent close to $90 on The Crew. I think that depending on the cost of Wild Run, if it is in the $25-30 dollar range, season pass holders should be given half off on the expansion.
Here is what I would like to see happen and why. Now given that Ivory Tower has put many hours into the game reworking what appears to be everything, I believe that they should be fairly compensated however I also feel that seeing how I've already spent close to $90 dollars on The Crew I shouldn't have to spend any more money. Many people like me have already spent $60USD for the game and $25 on the season pass another $30 makes this game over $120 with tax.
I saw from a Ubisoft employee that the Wild Run will NOT be free, now I personally see this as a downside for the overall game as many people will not be willing to spend another $30(guessing) on the game and some may even leave the game completely.
