I always score my list how i want. 10 and 9 for me is equal, with differences 10 i want to replay someday(like reread waifu route), and 9 was enough for me.
That stupid and affect overall score? Yes. But that not my problem, because site(also Mal) does not provide me custom lists.(Btw i use "Stalled" for nukige wish list, "droped" for normal wish list, "playing" for TL in process, and "wish list" by itself for diffrent category wish like vn with marriage or osananajimi). Maybe soon i will use 1 and 2 scores to tag something for myself(Lo vns in nukige wish list?)
Yeah, i know how that sound. But anyway scores means nothing, never look at it when choosing vn.
