There was some (huge) magnificent 40K scale Warlord Titans on display at Warhammer World.
The Warlord appears to be the most common class of Battle Titan in use by the Titan Legions of the Imperium of Man, and many Adeptus Mechanicus Forge Worlds field their own patterns of this class.
Another excellent Warlord Titan.
I sometimes think I would like to get a Forge World Titan, but then I think they are quite expensive (usually in excess of £1000) but would I have the skills to make and paint one, would I have the time? Probably not. So it can remain a dream and I can admire those that are on display at Warhammer World.
