HD now have a softspot for me, but Original if first time playing only for the original factor.

in my opinion original is better

hd has some solid out of bounds areas i dont remember base game having but base game trees are more climbable

Play original. HD has a lot of boundary and collision issues, some of them cut off paths available in original.

For a moment there i though i ended on the Half-Life 1 forums...

I prefer HD

I prefer HD, Nightdive did an awesome job on this one lol.

Shotguns in HD aren't lever-action, minus points for that from me

both are great but idefinitely think HD is the way to go. its still got a retro charm but with the benefit of a lot of additional details on the weapons, enemies and enviroments. this thread is the first ive heard of differences in terms of out of bounds areas but if that wasn't a big deal in my experience

I was wrong, HD shotguns are lever-action, but it's harder to see when you flip them at standard FoV

OG has a ton of charm. HD is great too but it's just subjective.

HD only for the weapons.

OG

I prefer OG, not being quite able to make out what you're shooting at (what's wrong with the scientist's face for instance) can be pretty freaky, and the low poly aesthetic in the environment makes the whole thing feel wrong in the best way possible, especially if I turn the resolution down

I'd say play OG first then HD.
