A few more things to add to it. You could leave the same ranking system and sell it as a expansion for dogfight so when you log on you chose to go to ww1 era or to go to ww2 era also you could keep a ranking system like the dogfight now for who is the highest ranked or who is ranked number 40,000 it could be where if you have a acount to dogfight when you log onto your dogfight acount and you buy the expansion it automatically ads your acount to dogfight 2 and your name and you start out as a asprent again but just in dogfight two. And joe I bet ther are 4000 or more dogfight players out there thinking we need a ww2 dogfight lol I put this out for a suggestion becuse loui inspired me by asking for a p51 but I decided that a p51 should not come in st the beginning if the game but latter on make people rank up and get more money then they add p40 and rock wolf then the hurricane and maby a diffrent typ of bf109 then we add the p51 c and 262 jet. O and like in dogfight all the planes should be farly equal so you can fly a spitfire and fight a me 262 jet. The reson I go with the p51c is becuse it's loui's profile pic and it looks nice.
