VGT Expansion
VGT Expansion is a Forge addon for the 1.12.2 GregTech Classic setup that adds GT4 content and makes early progression somewhat harder.
What it does
The mod ports parts of the GT4 feature set into the GregTech Classic line, using IC2 Classic and Vintage GregTech as its base dependencies. The author describes it as an early beta that is not yet a full port, so some GT4 features are still missing and parts of the work continue in later updates.
Several recipes were changed on purpose to raise the difficulty, and certain machines are harder to reach. The addon also includes smaller additions such as extra batteries, more fuel types, useless material items used as examples, and an oil well that yields four crops. Required dependencies are IC2Classic and MixinBooter. VGT Expansion is open source under the GNU General Public License v3.0 or later, and the source code and issue tracker are public.
Key features
GT4 content port
Adds parts of the GT4 content to a GregTech Classic setup, with the port still incomplete.
Harder progression
Several recipes were changed and some machines are harder to access, so early game progress takes more effort.
Extra fuels and batteries
More battery types and additional fuel types are included among the smaller additions.
Oil well crops
An oil well that produces four crops is one of the added misc items and machines.

Use cases
Who it’s for: Players who already run GregTech Classic on Forge 1.12.2 and want GT4-style content with harder early recipes. Server owners who want a tougher technology progression can also run it.
How it compares
GT4 Reimagined targets Forge 1.16.5 and is open source under the GNU Lesser General Public License v3.0 only, so it does not share VGT Expansion's version. GregTech Experimental is open source under the GNU Lesser General Public License v3.0 or later and also runs on Forge 1.12.2 with client and server. Epimorphism Core is open source under the MIT License and runs on Forge 1.12.2 with client and server, but it is a core library rather than a GT4 content addon.
