I just downloaded the title based on your post. I own the first game (acquired with free Google Play credit. I rarely pay out of pocket now that I earn free credit and wait for sales) after buying it again for my LG Optimus G. The first game ran well enough on my old iPhone 4 and iPad 2, but the game ran like garbage on my vastly superior Optimus G. So here is hoping that ASM2 runs as advertised rather than being a disappointment.
I actually logged in to talk about this. The game is one of the best I've ever played in a cellphone since ever, and having owned the first game as well, it's a vast improvement on that one, there are though some things I should war you all:
The game requires constant internet connection: Which I think it's lame, because I'd like to play outside with no internet connection and at travels.
The graphics here are superb: I love the graphics here, but I can see why it wouldn't work well in an iPhone 4 or an iPad 2. I also have the first game and I used to play them with my old iPhone 4 and iPad 2 devices, I can't see how this game would work with them now, can't talk about your LG Optimus though, since I never saw one.
I love the gameplay, but the web slinging shows old problems: The web slinging comes with problems that we came to expect, that is, the web is sticking to the clouds. With that said, the combat with thugs are cool as hell, I'm truly having a blast playing this.
The Hero or Menace system in the iOS game: It's pretty great. When I stopped playing, I had citzens cheering at me while I was signing the autograph to a fan girl. I loved the car chase part that I've played but I suck at getting to find thugs after I get a mission to find them.
Overall, I feel it's a vast improvement over the first game and I'd recommend you having an iPad 4th gen or superior to play it, or an iPhone 5 and above.
