Actually, there are four modes... Casual, Normal, Hardcore, Insane. I am assuming you are on Casual, as it's your first time through. Trust me, it gets easier after you get the hang of it. Casual and Normal will be easy (after you get used to the game), but Hardcore begins to be a Challenge, and Insane... well, almost everyone who has finished it says they probably won't do it again!
Actually, I don't think the Insane mode on either Gears is as hard as the hardest setting on some other games. I was able to play through them by myself, without many problems.
And then there are games like Ninja Gaiden, which on the normal setting is hard as ****!
