My "Order":
1). Games (99% of the time the words "games" and "rpg's" can be used interchangeably, in my case).
2). OST's
3). Strategy Guides
4). Other/Misc.
*NOTE* that, for me, "2" & "3" are tied...and barely under "1".
and "4" is a long way from "2" and "3".
So my "interest levels" (on a scale from 1 to 10) would be:
"1" = 10/10
"2" and "3" = 8/10 and
"4" = 3/10
How about for the rest of you?
