Ok, I'll bite. 

First off, I'm a complete noob when it comes to JRPGs.  I've never been into them.  I have never played a Final Fantasy game, and I've never even played Pokemon.  So I'm coming at this with a completely fresh perspective. 

The trailers for Star Ocean: The Last Hope really made me want to buy the game.  The graphics looked awesome, the music sounded cool, and the storyline seemed epic.  I didn't realize that Lymle would be the most annoying thing I have ever seen/heard in a video game, or that all any of the characters would ever talk about is how we're all friends.  You're my friend, I'm your friend, we're all friends, can we be friends, blah blah blah blah.  It got so sickeningly sappy I couldn't stand it.  The CGI stuff looked pretty awesome, but the in-game graphics were pretty terrible a lot of the time AND the game was plagued by crashes during the end of the battles.  I found out when I was on the 3rd disc that if you turn the resolution down on your 360 it gets rid of the crashing, but that was too little too late.  If you're going to make a game that crashes so much, put save points more often than every 2 hours of gameplay.  One thing I will say about SO4 is that the combat was ALWAYS fun.  I never got sick of grinding and replaying areas, and I never got sick of tweaking my characters.  But the story was stupid, the dialogue was stupid, and the game in general just became boring.

With Infinite Undiscovery, which I'm only half way through right now, I feel like I'm playing a much more polished game.  The graphics aren't a whole lot better, but that's about the only complaint I have.  The dialoge, while still dumb at times, is at least a marked improvement over SO4.  I actually feel the need to pay attention to what they're saying because they're not all gushing about what good friends we are all the time.  And the story is actually a cool idea.  I actually care what happens at the end of this game.  By the end of SO4, I just wanted it to end.  I thanked my lucky stars that I beat the final boss on the second try.  All in all, IU feels like a more complete game with a more thought out story line and more complex characters. 

Just about 5 hours into Lost Odyssey, and I already can tell it's worlds better than both SO4 and IU.  The controls are a little annoying when walking around in some areas, but other than that, I am absolutely LOVING it so far.  I can already tell that it may become one of my favorite RPGs of all time.  The graphics are good, the story is good, the battles are fun, and the dialogue doesn't sound like a Japanese to English translation.

So I went from never playing JRPGs to owning three different ones all in one year.  Lost Odyssey is by far my favorite so far and I just started it yesterday.  Of course these are just my opinions.  I'm not begrudging you yours.
