I'm in my mid-thirties, but somehow missed this when it came out, so first time playing. It's great. It's got that old-school difficulty, and you may find you need to save-scum to prevent the urge to rip out your hair, but with the possible exception of mobs of paratroopers who are all highly resistant to having a full clip from the MP40 emptied in their faces, it mostly feels fair. Some aspects seem a little bit pointless... like picking up treasure; beyond saying "oh boy, I got all the treasure," it doesn't seem to add anything. There's also no unlockables to be had for beating the game, as far as I can tell. Technically it's a little bit temperamental. Loading occasionally caused me some issues, sometimes refusing to load the file I'd asked for, and sometimes enemies would get stuck behind doors, or on one occasion would explode into colourful rods(?) rather than a corpse. At least the game worked though! which is more than I can say for Steam, when I bought it there. Minimal fiddling, and it was running. Also, after a very challenging campaign, I found the final boss to be easy - an anti-climax, but I've found this to be the case with many FPS games of the time. Aside from that, it's just so, so much fun cutting through the undead with WW2-era weaponry, so much fun trying to tactically pick through the levels rather than go in all-guns blazing, and it's a game that knows what it is - a campy, action-horror romp - it never takes itself too seriously. Oh p.s. the forest mission - it's fully as frustrating and difficult to figure out some parts as some people say. I think it was more annoying and fiddly than the train mission in San Andreas - for real. Makes up for it with the Norway, level which I thought was especially awesome.
