Ok first off, I know there two different genres of game. But for me, I really only want 1 iOS shooter right now. I didn't really like NOVA 1, so is 2 much better? What about Shadow Guardian?
I haven't played NOVA1 or NOVA2, but NOVA2 should be better graphic-wise, gameplay-wise etc, but if you're not into sci-fi shooters, then you probably still won't like it.
