I forget if I've posted in this thread already, but it probably deserves being mentioned again that The Mark is quite bad.
It has one redeeming quality in that the writing is dumb garbage that you can snicker at on occasion.
Beyond that, it's an overwhelmingly bland, dull, generic budget PC FPS from 1999 released in 2007 that fails at basic, fundamental concepts such as movement and aiming.
It's also such a mess with its headbob, FOV, and messed up aspect ratio that playing it made me feel physically uncomfortable.
For a game to get any worse it would have to manage to somehow inspire genuine hatred in me. Because i don't hate The Mark. It's just a terrible, really bad travesty hack job.
