Product notes
Anniversary Edition Complete Game Guide

This guide is positioned as the all-in-one companion for Skyrim Anniversary Edition. Its step-by-step approach covers more than just the critical path, and the 2025 update note suggests the content is current. The guide is brand new, which is a nice change if you're used to buying used strategy books. The main limitation is its price point: it's the more expensive of the two, so it's best for players who know they'll use the depth. If you're a completionist or a first-time Dragonborn, the purchase makes sense; if you're just curious about the main story, you might find it more than you need.
Doom 3 Prima Official Game Guide

This is an official Prima Games guide for the 2004 PC release of Doom 3. It's a straightforward companion for finding secrets, understanding enemy stats, and getting through the campaign. The condition is Good, so it will show some edge wear, but the content remains complete. The low price is the selling point: you get a piece of gaming history and a functional walkthrough for a small outlay. The limitation is that it's tied to the original 2004 version, so anyone playing a modern re-release or heavily modded build won't have those specifics covered.
Final choice by use case
If you're playing The Elder Scrolls V: Skyrim Anniversary Edition and want a complete guide for every quest, collectible, and crafting system, the Anniversary Edition Complete Game Guide is the better fit. If you're playing Doom 3 on PC from the 2004 era and want an official, inexpensive strategy guide with maps and secrets, the Doom 3 Prima Official Game Guide is the one to pick.
