I actually LIKE the new updates. They need your money because Kingsisle only has one game and it's this one. They're trying to make new better updates soon and they DO NOT want your wallet.
Wi-fi connection is bad for your internet because there are 2 or more devices trying to get internet and sometimes they interfere with eachother just like if you bump heads with another person. It could cause crashes while not playing a game either.
Bu without the membership your gameplay is totally unbalanced and you can't get to high levels and have better weapons and etc. It IS fun when you have the membership though.
