Playing Shadow Warrior (the original, not the remaster) on No Pain, No Gain.
Crap hitscannerish saveload-fest combat (Build FPS? with crap combat? YOU DON'T SAY!), weird and pretty unconvincing weapon selection (also, sticky bombs 4 years before Halo? nice! it's a pity they are so worthless here). Surprisingly well done kinesthetics, almost Realms_of_the_Haunting-grade. Really well done and immensely enjoyable level-design and encounter/situational-design, with puzzles and stuff, almost on par with Cybermage (yeah, I know it's a weird comparison, I was surprised as well), which singlehandedly saves the entire game.
Compared to Blood, not as artsy-fartsy, but much quicker in terms of combat (in Blood, combat is a slog due to the gazillion of little and oh-not-so-little delays, permeating almost every aspect of it) and with MUCH, MUCH better level layouts and situational variety (teh puzzles!).
Overall, a good, really fun and enjoyable-on-a-basic-level game, which falls (or maybe doesn't fall, haven't completed it yet) only a teensy bit short compared to Cybermage. Not a (gasp!) artistic statement (in contrast to Blood) in any way - but the gameplay here actually strongly delivers on it own (again, in stark contrast with Blood), even if primarily through exploration and not the combat mechanics themselves.
