I also think it's interesting that the only villains to make the list are from suikoden 2(Luc and Yuber also being in 1 and 3), which I think shows how poorly developed more recent villains have been, although I think Brandeau was pretty cool once you got some backstory for him in tactics.
I agree, Euram was a cheap imitation of Snowe with added 'comic relief'. The Godwin's copied the racial purge of Falena idea off of Windy and her attempt to clear out the Elves etc in the Scarlet Moon Empire. And Childerich= A poor mans Luca Blight as Dilber is to Ain Gide. While Dolph personality (or lack of it) hasn't been done before in the Suikoden series (that i can recall, correct me if i'm wrong) he is just like any other mysterious and over powered hence man we would find in a lot of other RPG's. I would say that Lord Barrows was the most interesting villain in Suikoden V for me, I like his evil manipulations even though it was obvious from the moment you see him that you cant trust him.
Haha, I kind of think the opposite way. Snowe, to me, seems like a Euram prototype. Though I can see how Euram seems like a Snowe clone, Euram has a lot more layers to him if you recruit him and find out his backstory through investigations and comment box letters.
I never thought of Childerich as a poor man's Luca, but then, there were enough moments where someone went nuts that it didn't even occur to me that the "die pig" line was a nod to Luca.
Dilber Novum though... definitely a poor man's Ain Gide. Although I didn't laugh half as much at Ain Gide's death as I did Dilber's. Oh, it had nothing to do with the death itself. I just found the portrait they used for Dilber at the moment of death to be... a little too much of a carbon copy of the moment. And distracting.
Salum Barows was a sneaky fat bastard, wasn't he? He definitely was more interesting than the cold, racist Marscal Godwin and his retarded son.
