Here are Mead and the crew, taking a leisurely stroll through one of the dunjons in Realms of Quest V. Let there be color! This is great! In Realms of Quest V each dunjon in the game may have their own color styles.
For visual dungeon comparison with the previous 2 Realms of Quest games, below here is one of the dunjons in Realms of Quest III.
Realms of Quest IV had black and white wire-frame graphics, but much more features like traps, spinners, teleporters and other such things in their dunjons.
+ Here is the Dungeon Crawler version of Realms of Quest III with its blue dunjons.
