So PS2 games are a little more difficult to pick cause theres so many but Romance of the Three Kingdoms XI makes the top of my list.
Then of course the Devil Summoner series along with Nocturne, and my recently purchased Dokapon Kingdom is on the list cause its an amazing game.
And of course my all time favorites the Persona series, a must own for any rpg player.
Then theres Phantom Brave & Makai Kingdom by NIS wich are two great srpgs.
Then theres last but not least River King which is quickly becoming one of my favs, and Sheperds Crossing im not to sure about but it seems to be pretty good, so whats your favorite ps2 titles???.
I always liked kingdom hearts, mgs 3 and cold winter. I am sure that there are more, but I cannot remember what I have in my collection.
Jak & Daxter trilogy, Metal Gear solid 3, Persona 3 FES, Persona 4, Dragon Quest 8, Suikoden V, Okami, Dark Cloud 2, Oden Sphere, Culdcept, Capcom Classics Collection 1 & 2, SNK Classics Vol. 1, Shadow of the Collosus, Beyond Good and Evil, Final Fantasy XII, Soul Calibur 3.
Well that more or less covers it. Honestly I have to realy like a game to buy it, so these are just best of the best in my collection.
Culdcept is a great game i also own it on the 360 Culdcep Saga and there both very good hybrid games, Oden Sphere im still looking to get havent found it yet, but good choices.
Shadow of the Collossus will go down as my favorite PS2 game.
Makai Kingdom - "SHUCK IT!!!"
Such a random reference, but NIS filled the SRPG void for me back then. Then I got my friend hooked on them.
So is Shuck it a good or bad thing for Makai Kingdom cause to me its almost exactly like Disgea.
A 360 list was too hard for me but a PS2 list is easy because I haven't played it quite as much and mainly bought only exclusives.
1. Dragon Quest VIII
2. Culdcept
3. God Hand
4. Okami
5. God of War series
6. Ratchet and Clank series
7. Vanillaware's games Odin's Sphere and GrimGrimoire
8. Killzone
Well i know two that you mentioned i dont have and want Odins Sphere and Grimgrimoire.
There are so many great PS2 games that there is no way I can list them all. But some that come off the top of my head are Klonoa 2, Katamari Damacy, Psychonauts, Okami, and many more!
That reminds me i need to get Okami thats an awesome game.
