TLDR: Zero-K and BAR are based on the same FOSS engine. Zero-K is less micro with better unit AI. BAR delivers a more vanilla and micro intensive Total Annihilation experience.
Supreme Commander is proprietary closed source and has some different mechanics. Larger but worse maps.
More modern graphics and less unit types but more micro opportunity. Also zero k has buildable terrain in the form of ramps and walls. Bar has terrain deformation but can’t actively do it with contractors.
Idk I haven’t played Zero K but it’s a good rts as well.
How does it differ from Zero-K or Supreme Commander (or any other TA clone)?
