Theres just a helluva lot of Jrpg hate around not just in this thread but in general. I like the Fallout series but cannot stand Oblivion, I just found it boring most of the time. Just because alot of western rpgs are more "realistic" and familiar i.e their settings are medieval fantasy most of the time and thusly more familar to a western audience hence the term western rpg, doesn't automatically make them superior to japanese rpgs. If I'm honest I think Jrpgs are more fun because they're not limited to one setting which most western developers can't seem to move away from. The Japanese aren't afraid to try something new with different settings. It can range from being set in space, on world with a american western feel, being pirates but sky pirates or just being deeply in the occult and just pure mind-fuckery. Sure its not realistic but isn't that the point of a role-playing game to begin with?!
As for the "angsty teenagers" thing that keeps getting thrown around to discuss the traditional Japanese rpg protagonist, I'm sorry, thats utter bullshit. Of course, people say this because they seem to think every jrpg is Final Fantasy, particular number 7. I can think of a crap-ton of jrpg protagonists that are nothing like the "angsty" type. The protagonists from Persona's 3 and 4, Ness from Earthbound, Vyse from Skies of Arcadia, Lloyd from Tales of Symphonia, Laharl from Disgaea, Issac from Golden Sun....need I go on?
Let me ask this? Sure you may say its bad for about 90% of Jrpgs to feature young kids as the heroes of the stories but are you saying you've NEVER imagined yourself as a hero saving the world when you were younger?!
Now I'm getting off topic, sorry.
Anyways, yeah, seems abit like Bethesda having a needless stab as someone's already said. Ultimately its personal taste. You can like whatever you want to like, no-one's really gonna change that for you.
