It's a fantastic game. Always makes me think back to the first Christmas I spent in Canada. I took a train from Toronto to Winnipeg to visit a friend and played DW7 the whole way on the PSP. Didn't even get that far but thinking about the game and the section with the volcano gives me all sorts of sense memories.
I've been toying with replaying DQ4 recently, but I have paralysis when it comes to charging my 3DS and taking the big box o' games down from the cupboard.
