So with that regard you dont think that ufo is a very good ''game'' as well.Once you get plasma and power/flying armor the game becomes a breeze,untill you get in contact with ethereals that keep mindcontrolling you and silacoids that kill you in 2 hits,you wont have to worry about nothing really.Add in the hyperwave decoders and put them in all of your bases and you basicaly can detect every terror and battleship in the world.Sure it may have taken alot longer than xenonauts which is personaly for me the part you get wolf armor and completed lazer technology,but atleast by then you havent discovered every kind of alien and you havent yet met a single battleship by that point of the game.In conclusion xenonauts is based on the original ufo defense,expecting some flaws of the original game to not appear in this wishfull thinking.
