I think it was 14 days when I was 10. My V1 knock-off couldn't live more than 14 days. But seriously why put the limit to 14 DAYS? 30 would've been better.
I'm currently on 43 on my v4.5
My second highest is on my iD L at Generation 20
Then my P's is also at 20
My Familitchi got to 27 but then I got bored, and it broke. :\
My record for a P1 was something like 45 days. I was quite a bit younger and having a terribly uneventful summer, so I had time to dote on my Mametchi At that point though, he was so old and frail that he just went gently into the night.
I WOULD have had 30 generations on my V4.5 by now, but midterms struck a few days ago and I totally forgot that I'd left it sitting on my end table for a full 24 hours. Good job, Saria
