Did anyone else feel that new XCOM was actually, in a way, more difficult than the original? Before you freak out, here's my reasoning.
Deaths: in the original you received about a death a mission unless it was an easy mission and often more if it was a harder one such as a terror mission or battleship. It was also very easy to replace dead soldiers.
Countries: In the new game the panic system is highly volatile and when you have to respond to only one of the three countries panicking from abductions, you are very likely to lose at least one. Also, in the original you could fight to the last council country but in this you could only fight to about half were lost.
Squads: You go from the original's 26 maximum to the new game's 6 maximum. Yeah, big difference.
Aliens: Not quite as deadly as normal, but you always encounter packs of them which can be harder to deal with when they surprise you. Some are still deadly, mainly sectopods with their ludicrous health, but if you know how to exploit the AI you can safely handle them.
Soldiers: In the old game a rookie could be extremely useful for things like grenade relays, being a pack mule, acting as a psi-puppet, being a psi-soldier, or even operating a blaster launcher without accuracy playing into effect, but in he new one rookies are useless and squaddies are still pretty bad.
Money: Okay, if you didn't have an extra $10,000,000 by the end of the original you were spending ludicrous amounts of money. It was significantly more scarce in the new game. This was balanced out by other resources not being as important and scarce.
