The difficulty and quality of the last two levels soured my experience. I can hardly remember the game before those two levels. I had similar issues with the first Splinter Cell, but I gave up on that game. I was able to basically finish this one apart from the very very last scenario...

Anyway, if I try to remember really carefully I think most of the levels were quite good. I can't really remember much of the story apart from the terrorist version of a Che Guevara. Plot is silly, but whatever.
