Guilty here too, I'm currently 145lb although my weight will drop very quickly if I don't keep an eye on it.
I've always been thin but it's not doing me any good, it prohibits me from developing muscle and cannibalises them when I actually do and leaves me very drained by the end of the day.
I'm with a girl who is big and I love it, I'm an FA and love curves and jiggles-but I hate my body as much as it hates me; I don't see the man in the mirror as me.
Recently I have put on a few pounds and I've started to notice my belly poking out from my body and into my other half, and I can't explain what a good feeling it is, I'd like to feel that more.

I don't know about MMO especially as you'd need servers running and that could get expensive fast surely? But the feeder game sounds like one of the best ideas I've heard, tbh I've been hunting around for something along those lines-but after many failed Googles gave up. If you could get it onto iTunes app store you could charge a fair amount and sell globally.

I'm kinda unimaginative with mine-Phoenix Chimera on Xbox Live and Facebook, generally on live at the weekend as the misery of work means I gotta do stuff in week.
