NOTE: FC crashed on me before I got to night. Take that into account
Well, I actual bought fortresscraft today (not the best decision I've made, but oh well) and I'm gonna write a comparison of these two games.
It is somewhat divided, but FC takes the cake. There is good consistency in MC, but FC is mostly consistent with the exception of the pickaxe, which looks a bit out of place.
MC has the controls we all know and love, simple and easy.
FC on the other hand, is terrible. There is no explanation on the controls at all, and it took me 5 minutes to learn how to place a block other than steel plating. You use the bumper buttons (which feel uncomfortable versus the trigger buttons, which I believe should have been used) to place and kill blocks. To switch blocks, you have to use the control pad to navigate this god awful interface (press a button to select a category, trigger buttons switch through blocks but you can't go out of the category you are in. The category's also aren't named/organized in any logical way, and it's hard to see which block is next) However, it does have a nice mini map.... which you access by pushing down the left stick. Also, you can only set the sensitivity for both sticks, not just one. Since the sensitivty for the right stick is way to low, you have no choice but to turn it up, which combined with a lack of sneak (it might be there but I can't find it), causes you to fall off platforms repeatedly.
Technically, they are the same game. However, minecraft currently has more features (I have yet to see a minecart/redstone/wolf/creeper/spider yet in FC). FC however, has a 'goal' (Find relics that unlock TNT and stuff)
First of all, you must be connected to xbox live to play. And if you happen to disconnect accidentaly, it will save your wor- Oh, no it won't. It will trash your world, blame you for having bad internet (I'm serious) and crash on you. Also, if you don't have a world saved and press load world, it will instantly crash on you.
Overall winner: MC
FC could be as good as creative MC, but it needs a better control scheme and some technical issues resolved.
