Recently finished Blue Dragon didn't take a long time to beat.  Just took a long time to finally get to playing it again and finishing it since I first started it in 2010.

Gameplay-wise. The story is very interesting and the artistic style is very pretty. But the gameplay is bland and mundane.

Although we had a thread in this maybe 2months ago now I will still give an answer.

It is somewhere around 200 now.

Off topic here, but who is the guy in your avatar?

The Last Remnant is also in my backlog started it a couple of times but still haven't finished it.

I'm stuck at some part on which you have to fight six different spots. The battles are pretty intense and long, but the bosses are ridiculously overpowered. And the grinding in this game doesn't work like in other games, so I'm pretty much stuck.

Got nowhere near that part yet.  Only played it a couple of hours still on the first disc.

My advise is that you do heavy grinding on the first disc. Once you hit the second one, your Battle Rank will be so high you won't be able to keep grinding.

Depends what you consider part of a backlog. If it includes games I have no intention of finishing, then it's pretty big. If it doesn't include games I've given up on completely, it's about 10-20.

My backlog is between 6-10 if I put in games I own
It would be over 40 if I included games I don't own (yet).
