Oh no, misunderstood again. You are right of course, but my idea doesn't exclude challenges and hard gameplay. That's why I'd like to see better geoscape AI that's dependant on the difficulty more than in the original. On harder difficulties you can make aliens smarter, maybe even so that they try to avoid the player, or that they do unexpected things (like draw the player from a base to get very large UFO and when he leaves attack the base). However, on lower difficulties, you have less missions in the original. That sometimes leads to very hard gameplay because you need money from savaged ufos, and since they sometimes completly avoid your base and land on the other side of Earth, I suggest making beggining on lower difficulties easier by helping the player.
But these are just few ideas, I'm simply trying to take out the almost total randomness from the original x-com and make player feel like that the aliens know what they are doing.
