It is useless to keep updating every 2 weeks if their content is boring.
Your talking about a game with 3D characters plus you have animated scenes, getting an update every 2 weeks is pretty good. I dont know how many people are involved with this project, but you have devs making 20K up to 50K a month, an entire team which handle certain tasks, coding, sound/music (you get the idea) and it takes them 3-4 months (maybe even longer) to release an update and there's little when it comes to content, the dev is to busy changing the story, characters, over that time which breaks the game and require you to start all over.
With this game you could just wait 3 months then get the latest update and it would still have more content then 80% of the games on here that update once a month or once every 3 months!
