This is one of the most comprehensive packs available, often recommended for use with the Unofficial Crusader Patch (UCP). It contains a massive variety of skirmish maps designed to push the engine to its unit limits.
If you are downloading a full map pack, you might also consider looking into the Stronghold Crusader Extreme content or the unofficial patch. The unofficial patch, in particular, fixes many legacy bugs and can even increase the unit limit, allowing you to play on massive custom maps with thousands of archers and swordsmen without the engine lagging. Combining a massive map pack with these technical improvements creates the definitive Stronghold experience. stronghold crusader map pack full
