Would I recommend Half-Life? Hell yes. Would I recommend Half-Life: Source? Er, maybe. The original Half-Life was, and still is, an absolutely fantastic game. The story and how it’s conveyed to the player works extremely well, and the controls, gameplay mechanics, visuals, and sound are all phenomenal. Very few bugs, and certainly none game-breakingly noteworthy.
However, this is where Half-Life: Source fails. This game’s major problem is its glitches and bugs. Some minor, some absolutely game-breaking. On one hand, you have scientist’s AI screwed up, running into open fire, constantly shooting off their response lines. On the other hand, you have some parts of the game where the textures and models go ape♥♥♥♥, essentially simulating your graphics card melting.
Even with the bugs, the game does try to make it up with some enhancements thanks to the Source engine. The water effects are slightly better (although in my experiences it’s just extraordinarily shiny and reflective), and the lighting effects are significantly improved, although inconsistent when walking into an area that needs to load. However, the HL2 bullet hole decals make it possible to create magnificent works of art with your crowbar on walls.
Thankfully, the gameplay, controls, and overall look and appeal of the game is still there, unaltered. There’s no denying that the game is awesome. Half-Life in general is awesome. I just love how people on the GoldSrc version of Half-Life were complaining about the game having extremely old and outdated graphics, saying HL:Source is better in this field. Well, it’s not. A majority of textures and models are completely identical. Aside from the water and bullet decals, the games are visually the same, which is something I’m completely fine with. The regular version of Half-Life actually comes with the HD texture pack, something this port lacks. It essentially gives the game updated models to characters and weapons, and slightly enhanced textures in some areas. It’s nice, but not essential, which is fine.
Overall, yeah, go ahead and get it. If this is ever on sale for cheaper than the regular Half-Life, and you own neither, by all means, go ahead and get it. You (hopefully) won’t regret it.
