Yes, the genre of the show will be very confusing to the first time viewer.
The initial settings (single male vs multiple females, the character design and the comedies in the first few episodes) will make people think this is a harem show thus attracting the wrong people to watch. Needless to say, they will find the show unsatisfactory at the end because romance does not play a very important role here.
IMO, another problem is that the TV series is really made for the fans who had played the game. Admittedly, the studio had done very well to pack most of the story into 12 episodes. However, the pacing is very fast and occassionally can be quite confusing to those who had not played the game as some of the dialogues are omitted.
Anyway, let's keep our fingers' crossed for Air to be licensed.
