I personally prefer RPGs... mostly Japanese RPGs only because i have a strange bond with them. I do enjoy a couple Western RPGs such as, Mass Effect and Oblivion (I didn't enjoy Morrow wind too much) but I never found myself enjoying KOTOR or Jade Empire that much. I guess it's just the style. I really enjoy a good storyline and in-depth characters, if a game doesn't include this, I cannot get into it. That is why I'm skeptical on picking up the Japanese import of Record of Agarest War. I played the demo and I already was in love... but then I found out that you play as this guy, but that is only 1/5 of the story; you then pick a wife and it goes into the next generation where you play as his child... this repeats four times in creating 5 main characters which I don't like. All the cool characters I was introduced to are gone before you know it.
And to be more specific, I enjoy Strategy RPGs more than any other RPGs. Disgaea, Final Fantasy Tactics, Front Mission, and I guess Persona; I'm just a strategizer so I enjoy sitting down and calculating the best move. That is why I was not much a fan of Final Fantasy XII compared to previous games, it was a bit too hectic (that is also why I'm skeptical on picking The Last Remnant right away... that game just looks crazy). But that doesn't mean I hate the others as I do enjoy faster paced J-RPGs such as the Tales series and the Star Ocean series.
I also have a fondness for third person action games.(Metal Gear Solid, Splinter Cell, Gears of War, Resident Evil, Devil May Cry and YES! The Bouncer!)
