I voted for Multiplayer, mostly because without it, I personally believe that it will be become boring,fast I do not like being unable to fly with other human beings, it just gives me a thrill and more excitement to shoot a real person down not my computer .
However the multiplayer aspect is not the only thing that contributes to a long lasting game (obvously), Good graphics and realism makes me think "wow, so this is how it really is", I love realism. I always fly 100% realism however I do see the point that others have made about that it should be fun and I can relate to that, people aren't going to play a game that isn't fun!
Another thing that will prolong the life of JT is expansions, take CFS1 for example some members of my squad still to this day play on CFS1, and you know why? because we can mod planes, turn them into Jets and so on, we could almost continuously expand the game, and I believe that my squad will continue to keep playing CFS1 for this reason.
Great Job :yes: , and Good Luck Lads!
