For me your project is unique because you have mixed the best features of Silent Hunter,Aces of the Deep and FTL so months of waiting aren't a problem at all
,,Father" of UnReal World has been making this game for 20 years and he still has many ideas. He is making the biggest update to his game(quests,more ,,deep" NPC,new weather system,better graphic etc) and he always uses ideas of his fans to improve his project(just like you). I wish you to have the same strong will to continue the work but for me it needs only more complex and difficult combat(maybe difficult options in % will be good idea) and specific submarines for specific country(USA with Typhoon...?). Keep up the good work
