You are.

I only played it once. It actually took me ages to find Blonde, the final effect I needed, so after that I finished the game and didn't touch it.
Then I reformatted my laptop and lost errything.
I might get it again but it won't be the same.

i've completed yumenikki at least 10 times already

it's intresting enough to have a high replay value in my opinion

on rare occasions, i might start it up.

i've replayed .flow about ten times as many as YN though. fellow /fg/ts!

At first I played it for the excitement of exploring new worlds. Now I replay it for for the ambience of those worlds.

i don't know why but, i've played it a lot.
Even though i've seen the areas thousands of times, it's always so fascinating and creepy

Interesting... I think I might replay it for the ambiance soon, and I've forgotten the location of most effects by now.

I have played it many times, but I've only played through it all the way once. I've done the Uboa event about four(?) times.

As for .flow, I've totally lost count how many times I've played through. I've played all the way through v0.1 once, but the ones that didn't have an ending, I've collected all of the effects several times.

You really should play all of these games in the dark with headphones on, if you have the balls. It enhances the ambience substantially.
