I had to choose between 4 and 5 stars. I didn't think it was 5-star perfect because of so many spelling errors, but those errors didn't deter enough from the awesomeness of the game to warrant a 4-star, so I'm sticking with 5.  I loved being able to find all the allies and then promote all those players. Towards the end, I did have my 4-party core, but even then I switched a couple mid-battle for their unique skills when needed.  I'm looking forward to playing Epic Wings II soon.
