I play Pokemon games usually within about a month (I like to replay one of these these and/or play the new ones usually every year) I can usually finish a Final Fantasy Tactics replay within a few days if I'm trying but the typical playthrough when I'm just having fun is a week or two. Another old JRPG I replay sometimes is DBZ: The Legend of the Super Saiyan and the last time I played that (a week ago) it took me three days (with work) which was quite fast for me.
Took me about 3 weeks to play Fire Emblem: Sacred Stones back in January, and then maybe 2 weeks to play through Fire Emblem: Awakening (although I still pick this up to play new DLC/Paralogues, etc. but that's a different story).
I suspect it takes me longer to play through most games than the average gamer though as I have a full time job and additional responsibilities beyond that that give me very little free time.
