Both versions are the same price on Steam.

There is no cost trade-off for the reduced performance and limited assets compared to the original.

In some cases, this led to the graphics actually looking worse in the re-release.

The graphics from the original game were re-used poorly, often given only minor adjustments during porting.

Also, it's possible to stun-lock alien grunts at close range by beating them to death with a crowbar!.

marines can finally gun down Barnacles rather than ignoring their tongues and get eaten alive.

The NPC's AI is downgraded in comparison to the original version, even though the security guards and H.E.C.U.

There is also a major graphical glitch in the 'c2a4c' map (as a result of the 2013 update), rendering the game virtually unplayable unless the multi-core rendering setting is turned off.

The crowbar makes a metal-on-metal striking sound even when hitting wooden objects.

It is (rather infamously) possible to take down an Apache helicopter with a few Glock 17 rounds.

The shading gives some weapons a plastic toy appearance.

Some NPCs, such as the Black Mesa Security Guards, shows a chrome-like visual effect on their models.

It suffers from numerous glitches, which worsened when the game transitioned to Source 2013 in the SteamPipe update.

Of course, it's possible to make maps for the game if you manage to configure it properly.

It does nothing to demonstrate the power of the Source engine, other than showing that it's possible to port games and mods from the GoldSrc engine.

Opposing Force, Blue Shift and including Decay didn't get their own ports.

It's almost exactly the same as the original, except for largely inconsequential additions like ragdoll physics, replacing the skyboxes with 3D versions and improved lighting.
