If you want the single best big-budget open world you can buy cheap, it comes down to two games: The Witcher 3: Wild Hunt and Red Dead Redemption 2. Both launched at full price, both are now a fraction of it, and both are the kind of hundred-hour adventure people remember for years. Buying either is a great decision — but they feel very different, and one probably fits you better.
Here's the honest comparison: story, world, pace and value, and a clear call on which to play first. Live prices are in the quick-pick table. For the wider genre, see cheap open-world games; for the price tier, the best under $30.
The head-to-head
Story and characters
Both are storytelling high-water marks. The Witcher 3 is the best side-quest writing in the genre — even minor errands turn into memorable, morally messy short stories. Red Dead Redemption 2 is a slower, more novelistic character piece with one of the great endings in the medium. Witcher for breadth of great stories; Red Dead for the depth of one.
The world
The Witcher 3's world is huge, varied and dense with things to do. Red Dead's is the most detailed open world ever built — slower and more deliberate, more about living in it than clearing it. If you want density and pace, Witcher; if you want immersion and atmosphere, Red Dead.
Combat and pace
The Witcher 3's combat is merely fine but its quests carry it; the game moves at a decent clip once it opens up. Red Dead is deliberately slow — heavy, weighty controls and a measured rhythm that some adore and some bounce off. Be honest about your patience: Red Dead asks for a lot of it.
Length and value
Both are enormous. The Witcher 3: Game of the Year Edition bundles both huge expansions — 150-plus hours — and is usually the cheaper of the two, which makes it the stronger pure value pick. Red Dead is a 60-plus-hour single adventure and also sells far below its launch price. Neither is anything but a bargain now.
Platform notes
Both are cheapest as PlayStation discs, and both run on PS5 via backward compatibility (the Witcher has a free next-gen upgrade). If you're on PlayStation, either is a steal — see the best PS games under $20.
The verdict: which should you play first?
Play The Witcher 3 first if you want the best quests in gaming, more game for less money, and a world that moves at a healthy pace. Play Red Dead Redemption 2 first if you want the most immersive, detailed, unhurried world ever made and you have the patience it asks for. You genuinely can't go wrong — and at these prices, most people should just play both.
