GTA 6 vs Red Dead Redemption 2: What Carries Over, What Changes

🗺️ Curious how big Leonida actually is? See our complete Leonida map guide for the full regional breakdown.

Red Dead Redemption 2 is still widely considered Rockstar’s best-built game, which makes it the most useful yardstick anyone has for GTA 6. It’s not a coincidence — GTA 6 runs on an evolved version of the same RAGE engine, and multiple systems RDR2 pioneered are clearly being scaled up for Leonida. Here’s exactly what’s carrying over, what’s changing, and how the two games actually compare.

Quick Answer

GTA 6 and Red Dead Redemption 2 share the same core RAGE engine, significantly upgraded for GTA 6’s modern setting. GTA 6’s map is confirmed to be the largest open world Rockstar has ever built, surpassing RDR2’s already massive frontier — reportedly large enough to fit both RDR2’s and GTA V’s maps inside it with room left over, according to Reddit-shared scale comparisons of Rockstar’s open worlds. GTA 6 borrows RDR2’s NPC simulation depth, wildlife AI, and dynamic weather systems, but shifts them into a dense urban environment rather than a rural frontier, and swaps RDR2’s single-protagonist structure for two leads sharing one story.

Same Engine, Different Job

RDR2 launched in 2018 and became the benchmark for open-world immersion — every town felt handcrafted, NPCs ran daily routines, and wildlife behaved like it actually belonged in an ecosystem rather than existing to be shot. Rockstar effectively used RDR2 as a testing ground: systems like NPC interaction AI, wildlife behavior, and weather simulation were refined there first, and GTA 6 is now scaling those same foundations for a much busier, denser modern setting. The trailer footage backs this up directly — NPCs filming with phones, working out on the beach, socializing in nightclubs — the same philosophy of “living world” RDR2 pioneered, just applied to Vice City instead of the frontier.

Map Size: How They Actually Compare

Game	Map Status
GTA V	~75.84 km² (land + water combined)
Red Dead Redemption 2	Rockstar’s largest map before GTA 6
GTA 6	Confirmed largest Rockstar open world ever built

Nothing official on exact square kilometers exists yet, but data miners have described Leonida’s rough layout as roughly twice the size of GTA V’s San Andreas, and community scale comparisons posted on Reddit suggest both RDR2’s and GTA V’s full maps could fit inside GTA 6’s with space to spare. Treat exact figures as unconfirmed until Rockstar says otherwise, but the “biggest map yet” claim itself is about as solid as pre-release information gets.

Wildlife and Hunting: RDR2’s DNA, Florida’s Twist

RDR2’s wildlife system set the standard other open-world games still get compared to — animal behavior, hunting mechanics, and honor consequences for how you treated nature. GTA 6 is confirmed to include a hunting system directly inspired by RDR2, centered on Grassrivers, Leonida’s Everglades-style wetlands. It won’t match RDR2’s full depth — no horse bonding or camp management systems are expected — but Leonida’s subtropical setting offers something RDR2’s frontier couldn’t: alligators, invasive species, and the specifically Florida flavor of wildlife chaos that’s already shown up in trailer footage.

Storytelling: One Hero vs. Two

This is one of the clearest structural breaks from RDR2’s formula. Arthur Morgan carried Red Dead Redemption 2’s entire narrative alone — a single, deeply personal arc told through tightly scripted, cinematic missions with specific narrative beats. GTA 6 splits that emotional weight across Jason and Lucia, a romantic couple whose stories are really one narrative experienced from two angles, closer in spirit to how GTA V let players switch between three protagonists — except built around a relationship instead of three unconnected lives.

Graphics and Technical Leap

GTA 6 is expected to go beyond what RDR2 achieved on last-generation hardware, built specifically for PS5 and Xbox Series X/S from the ground up. Hardware-accelerated ray tracing, denser NPC populations, and more advanced weather simulation are all expected improvements over RDR2’s already-impressive 2018 visuals — a jump roughly comparable to what RDR2 itself represented over GTA V back in the day.

Frequently Asked Questions

Does GTA 6 use the same engine as Red Dead Redemption 2? Yes — GTA 6 runs on an evolved version of the same RAGE engine, upgraded for NPC density, weather simulation, and visual fidelity beyond what RDR2 achieved.

Is the GTA 6 map bigger than RDR2’s? Yes, Rockstar has confirmed GTA 6’s map is the largest open world it has ever built, which would put it ahead of RDR2. Exact size hasn’t been officially revealed.

Will GTA 6 have hunting like RDR2? Yes, a hunting system inspired by RDR2 is confirmed, centered in the Grassrivers region, though it isn’t expected to match RDR2’s full depth with systems like horse bonding.

Does GTA 6 have one protagonist like RDR2, or multiple? GTA 6 has two protagonists, Jason and Lucia, sharing one story — a different structure than RDR2’s single-protagonist narrative.

Is GTA 6 coming to the same platforms as RDR2 did at launch? No. RDR2 launched on PS4 and Xbox One before a later PC release. GTA 6 launches exclusively on PS5 and Xbox Series X/S, with no PC version confirmed yet.
