Debatable?

While perusing my usual online haunts, I came across Kotaku's post on IGN's Top 25 PS2 Games of All Time. Needless to say, I was immediately interested. Here is how their top 25 played out with respect to my library:

• I "own" 10 of the top 25 titles (explanation for quotations to come)
  
• Suikoden III was one of the first PS2 games I beat completely and thoroughly
• Kingdom Hearts was one of the few games I actually asked my dad to go out and buy, sounds like a stupid/childish idea but hell is it fun to smash those Heartless with my Ultima Weapon keyblade...
  
• I own Devil May Cry, but not DMC 2 or 3, but seeing as how they're the same series and approximately the same gameplay-wise, I claim to "own" this entry... freakishly badass game/series IMO
• Resident Evil is a series I've literally grown up with (since the days when my uncle would be killing zombies with a 6 year old me in tow), so I'm a fan of RE4, I'm in the process of beating it but it freaks the hell out of me so... I'll beat it when someone else comes over
  
• I own Dragon Quest VIII but have never actually played it (it was a purchase of my father's, not mine), though I've heard nothing but win for it so perhaps I'll tackle it once I'm done with FFXII (that's Final Fantasy 12, not the disgusting 10 part 2)
• I own Gran Turismo A-Spec (GT3?) which is again, the same series as a mentioned title (GT4) but not it exactly, I actually really got into it for awhile but I got bored of attempting (and mostly failing) licenses... I guess I'm just a sucky driver
• I own 4 of the top 10 titles
• ICO I have but haven't played (see Dragon Quest VIII point)
• I own MGS3 but not Subsistance, but the heart of the game (actual story, single-player gameplay) is what I'm in love with (extras are fun, but they can't compare with the actual game itself), and oh how I <3>
• Final Fantasy X was another one of those first few PS2 games I beat through and through just because I loved the game so much, I actually beat half of the game, put it down (and accidentally deleted the save file), and beat all over again from scratch
• And finally, there's my God Of War sitting at freakin' #1 at the top of the list, Kratos, you've done me proud, I'm still thoroughly pleased with this game and I'll be busting it out again very soon (once FFXII is over) to bash some more Greek baddies on God Mode... oh blasphemy...

And there you have it. Some interesting mentions on that list (that I don't own) include Twisted Metal Black (what were you thinking?! top ten? is this a joke?!), Shadow of Colossus (I actually really wanted to buy this one but never found the motivation/money), Okami (see Shadow of Colossus comment), and Tekken Tag Tournament (I loved Tekken 2 and 3 so it beats me why I don't own a PS2-gen Tekken title...).
I also would consider buying the game Rez, but... well... seems like it'll only be worthwhile to get/play it after I get hitched... It's more of a two-player type game... O.o
