While I bought VIP solely for Seven knights, which is updated well and fast, I may or may not continue to spend $20 a month on VIP. Yes, I fully enjoyed and utilised the mods brought out by TeamAR, and I think it was worth the initial payment, I do not think I will need it too often in the future. Reason being I already have a decent status in the game itself, paying $20 just for a slight advantage above what I can already do is a little steep. HOWEVER! If you are a frequent mobile gamer, the VIP modded games are very well made and updated frequently, hence if you have $20 to throw around OR you really just play that many online mobile games, then I would say the $20 is well worth the enjoyment you pay for. Like an earlier post has stated, if extension of VIP was discounted, then yes, I would probably pay for it. However at this point I am only using VIP for one game, and I feel as if I am wasting my VIP status, as I truly have no interest in the other games.
TL;DR
Get if you plan to use at least 3 of the VIP mods frequently, but if you only want one game modded (like me), may want to reconsider.
