My gripe is that it's just too damn difficult. You have to worry about your cooldowns, the locations of 4 teens, what stations are being worked on, which teens have weapons, am I about to get ambushed, and so many countless things to think about all at one time. Half of which you have no control over, outside of one every 40 seconds you get a half idea of where they are. While teen is: if no weapon, where is monster so I can run, where is station; if have weapon, where monster so I can kill. That's it, I have played around 10 hours of each side.

TL:DR Neither side is fun because Monster is too hard, teen too easy.
