Not really a surprise.
Regarding your comments on the gameplay. I'm not sure if UC or UC2 had better gameplay. There was more platforming in UC2, which made it a lot more fun the first time through, but less interesting in later play throughs. On the other hand, the constant gun fights of the first game just got frustrating, though with more checkpoints, the stealth mechanics, and cheats of the second game I could welcome a little more shooting.
"Now, a fun game should always be easy to understand - you should be able to take one look at it and know what you have to do straight away. It should be so well constructed that you can tell at a glance what your goal is and, even if you don’t succeed, you’ll blame yourself rather than the game. Moreover, the people standing around watching the game have also got to be able to enjoy it." - Shiggy
