These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: No One Lives Forever
Anticlimax Boss - The last part of the second game, sadly. Not only there's Volkov in the wheelchair (see Villain Decay), but the very last enemy you have to confront is just a Giant Mook, maybe a little more resistant than the others, but he doesn't even get an energy bar. Even Isako may qualify; the second and last encounter with this boss is almost boring, compared to the battle inside the tornado in Ohio.
Complete Monster - Volkov particularly stands out for his cruelty and the way he casually kills henchmen just to vent his anger (although this is sometimes played for laughs). Also the Director and the Baroness - the latter has no Freudian Excuse, even taking into account the harsher detail of her father being involved in a pedophilia scandal. Cate's past is similar, but she took a better path.
Crowning Music of Awesome - The main theme of the first game. The theme of the second game, while good, is not at the same level, but you can hear the first theme during the ending credits.
Germans Love David Hasselhoff - The first game was quite successful in Germany, thanks to many positive reviews in the German gaming press, and probably also to its taking place in several German locations. So much that, while the first edition had only translated subtitles, the local publisher took the effort to also dub the game for the GOTY rerelease.
Curiously, at first there seems to be a Retcon, since you assume Volkov's condition is due to his fall in the icy pit near the end of the first episode, apparently ignoring the very last scene of the same game with him in perfect shape, meeting the Director. You also might end up assuming that his first meeting with King Pierre as well as a letter you can find towards the end of the second episode, where he claims he got injured in a skiing accident while on vacation, is a justification he gives to cover his failure. Then, at the end of Contract J.A.C.K. you find out that it's all true.
