about the time tainted kingdom came out, krin released 2 things about sonny 2, one on armor games and 1 on newgrounds. both agreed it would take about 1-2 months AT LEAST to finish sonny 2 (apprently krin started work immediatly after sonny was released) but the newgrounds post said more stuff. such as each class would have its own skill tree, and what the three classes would be. also the loading screen was released, which has a blue girl zombie on it, a new character 9also the first girl zombie to be seen in the series. the only girls in the first one were these 2 witch like characters that were bonuses for beating the game and getting to illusion valley). as we all know it has been nearly 3 months since tainted kingdom came out, and 3>2 so it could come out any day now. be prepared, but remember, it could still take a while. as a game creator myself i know how easy it is to think "i only have 1 or more things left to do" then a month later realise you accidently added 20 fefatures you weren't originally intending, without starting on the 2 you wanted to do, and having 15 ideas still left on new stuff you want to do.
Sonny is a great RPG game. It has everything it needs to be great. However, I bet that Krin put a lot of time into and is still thinking of other things to put into another. There will be another sonny, it will just be some time.
Yes, it's not going to come out anytime soon, but they are making it. I do hope that the second one will be longer than the first, as the sequels which come out right now tend to be shorter than the prequels...
I think this game is really good and i think there definitely should be a 2, but i seen people go crazy over the game. I gave it a 10 but, wow, its not that big of a deal.
