Well we know who came first, SCB was released for Windows in May 2010 and MK came out in Sep 2011, but which one do you like better. Don't vote unless you actually have both games (as if saying that will actually make a difference). MK has benefited from over 4 months of life on the AppStore and has received frequent updates. MK has more levels, more weapons, more unlockables and online multiplayer. It also has IAPs which are not necessary but some people hate anyway. More weapons and the ability to upgrade them, combined with the added perks and heart upgrades makes MK a much more forgiving game. SCB has just three levels right now, three game modes, and no mp as of yet. SCB is harder with wicked fast unforgiving gameplay. But man is it satisfying to beat your high scores! Both have exceptionally high fun/addiction factors. Both have spot-on controls with MK being a little floatier and SCB being slightly faster.
