I also kinda enjoy.......I'm being serious about this now........Hunt Down the Freeman........it's like The Room of games, poorly made, horrible acting, etc. But the fact that it's so so so horribly made makes it kinda enjoyable. But that's just the crazy Half-Life fan side of me talking. Plus it's the only game that shows at least something like the 7 Hours War might've been like. So the difficulty is kinda warranted in that sense, if the Combine could take out all of Earth's military forces in a mere 7 hours, you can be sure a single man who was in the hospital would be a cakewalk for them. That being said, you sure as hell could make a more convincing 7 hours war role-play in Gmod, assuming your computer is beefy enough to handle 200+ mods, gigantic map with full interiors with furniture, and hundreds of NPCs constantly fighting. Which despite being a source engine game, can be rather expensive, hell my $1000+ gaming laptop was lagging when I tried huge projects like that, and it could run RE2 flawlessly. Funny thing, when my laptop was working, I often went into Gmod with the YouTube mod, and built a living room in a house, with a couch with a buggy chair in it so I could sit down, and watched Night of the Living Dead, and Dawn of the Dead both in full. Sure I could've just went on YouTube and watched them normally, buuuuuuut, eh, it's enjoyable like that. To be completely honest, it's kinda surprising how Gmod became so popular, I mean hell, you need to buy 19 other games (20 if you want maps that use Black Mesa content) to even be able to get every mod and map working properly, which including Gmod, and the various "Free to Play" games, makes a total of 30 games you have to install and a total of around $195 for every game you need to buy, so along with a good computer you also need to have a pretty large drive that's at least over 250 GB in order to install each game and also get lots of mods.
