How to get Total War: Medieval II – Definitive Edition running today

If the game lags badly when castle walls are destroyed, a problem on Windows 10 and later, install the unofficial M2EX patch, which also fixes many bugs, shortens turn times and improves stability (PCGamingWiki).
To install M2EX, back up the game folder, install the latest Visual C++ redistributable, extract M2EX.7z into the game folder and start the game with M2EX.exe.

Synopsis

A strategy game set in medieval Europe and the Middle East that alternates between a turn-based campaign map, where you manage cities, armies, diplomacy, the Pope and dynastic heirs, and huge real-time battles and sieges with thousands of soldiers. The Definitive Edition bundles the base game with the Kingdoms expansion and its four extra campaigns.

What people say

Critics at release called it one of the best entries in the series, praising its scale, its tense battles and how vividly it brings the period to life, while noting a mediocre campaign interface, occasional unit AI failures and balance issues that needed patching. Players still rate it very highly, and its modding scene keeps it alive with total conversions such as Divide and Conquer. Common complaints today are weak campaign and siege AI, clumsy unit control, bugs that were never fixed and dated presentation next to newer Total War games.

Playability today

Playability runs from 1 to 5. It is the average of two parts. Each part starts at 1 and climbs to 5 as more of its checks pass. Read the method.

✗Controls feel natural on a modern controller or mouse and keyboardPlayers often find units hard to control in battle, and it lacks quality-of-life tools from later Total War games; there is no controller support. Source: metacritic.com, pcgamingwiki.com.
✗Menus, text and interface are clear on today's screensThe interface stretches badly on widescreen resolutions, and even release reviews called the campaign interface mediocre. Source: pcgamingwiki.com, metacritic.com.
✓Saving is fair: free saves or frequent checkpoints, little lost progressYou can save freely on the campaign map between turns, so little progress is lost; evidence on this point is thin. Source: pcgamingwiki.com.
✓It teaches itself: no guide needed to make progressCritic and player summaries raise no common complaint about learning the game, and the campaign builds up from a small realm; evidence on this point is thin. Source: metacritic.com.
✓Pacing holds up: little grind, filler or forced backtrackingCampaigns grow livelier with events like the Mongol invasions and the New World, though city management can feel like a chore. Source: dedoimedo.com.
✗Camera and movement never fight the playerThe battle camera is stiff by modern standards, which is why the popular M2EX patch replaces it with a new one; evidence from player complaints is thin. Source: pcgamingwiki.com.
