Resolution discusses the similarities and differences between Age of Chivalry and Pirates, Vikings & Knights II.
From the article: "Both titles are equally marvellous, but cater to wildly disparate play styles. The splendid humour evident in Pirates, Vikings and Knights II is little condolence for the fact new players are slaughtered without compunction, whereas Age of Chivalry is less instantaneously intriguing but more lenient in challenge. Anyone with a spare hl2.exe owes it to themselves to check each of these out, especially since it's a time of substantial updates for both. To say there's no real gameplay variation other than the character movement is probably a little unfair to the developers and undersells the mods somewhat, but it certainly plays an important role in shaping these two experiences. So, does slow and steady win the race? That's up to you."
