I've never really played a game of this exact type before, so when I started the game and it asked me to "choose easy if you've not payed a game of this type before", I chose to go with this difficulty. Hearing about people having to start over after 9 - 10 hours of gameplay also pushed me towards this choice.
My question is that if anyone knows what exact differences are present between the different difficulties?
Is it things like alien/soldier health, credits earned etc.? Does it also in anyway change the number of missions? (as there is not really a "story"). I ask this because after only a few hours of playing the game I'm at the the first alien base.
