Choosing a strategy reference for a video game usually means picking between two very different experiences: a small, affordable walkthrough for a game you already love, or a comprehensive, brand-new manual for a huge open-world adventure. The best strategy reference for your shelf depends on what you'll actually be playing, not just what looks impressive.
Here we compare the Doom 3 Prima Official Game Guide with the Red Dead Redemption 2 Ultimate Game Guide to help you decide which one belongs on your shelf.
Quick Verdict
The Doom 3 guide is the pick if you want an inexpensive, level-by-level companion for a classic PC shooter and are comfortable with a Good-condition cover. The Red Dead Redemption 2 Ultimate Game Guide is the pick if you want a Brand New paperback that walks you through every mission and secret in a massive modern open world.

Product Notes
Doom 3 Prima Official Game Guide

This official Prima strategy guide for Doom 3 on PC, written by Bryan Stratton and Craig Wessel, is a full level-by-level walkthrough. It includes single-player maps, multiplayer hints, stats for characters and enemies, weapon overviews, storage cabinet combos, cheat codes, and the locations of the BFG and hidden secrets. That makes it a strong choice for anyone replaying id Software's 2004 shooter and wanting a dedicated companion. The limitation is physical condition: the cover shows minor edge wear and corner scuffing, so this is a Good-condition copy rather than a fresh one. At $4.99, you're getting a lot of focused reference material for a classic PC game without spending much.
Red Dead Redemption 2 Ultimate Game Guide

Written by Ivan Parker, this Brand New paperback presents itself as an essential roadmap to Rockstar's open-world Western. It walks you through the full campaign, offers mission tips, and aims to help you uncover every secret and explore the entire game world. That makes it an excellent fit for a first-time playthrough or for returning players who want to complete every objective. The trade-off is the price: at $30.25, it's far more expensive than the Doom 3 guide. You're paying for a clean, never-used copy and the breadth of a much larger game. If you only need light pointers, that extra cost is hard to justify.
Final Choice by Use Case
- Choose the Doom 3 Prima Official Game Guide when you're playing the classic PC shooter and want a compact reference for maps, secrets, and cheat codes at a very low price.
- Choose the Red Dead Redemption 2 Ultimate Game Guide when you want a Brand New paperback with full walkthrough coverage and mission tips for an enormous open world, and you're willing to pay more for it.
Either way, you'll have a useful strategy reference that matches the game you're playing.
