Well I started catching Yahtzee's cometary on his old ass sites, back before ZP became a thing. I mostly found him because of being poor and searching freeware games, how I found the freeware games he published, found I liked his work generally. Saw his cometary later, liked that fallowed on and off for a long time. I'm also one of those strange persons who had the occasional brush with him online, commenting in various forums around the internet long long ago, before ZP even. I liked him even a bit back then, even if most people saw him as a total self absorbed prick.
I caught on to ZP shortly after it hit if I recall correctly I saw a few episodes when there were just a few videos. But this was about a year after my mom died, and between then and 2010 are a blur to me because of how much influx my life was.
Still I keep up to date with ZP, and EP for that matter, also now Judging by the Cover is something I somewhat enjoy. I just get behind fairly often and have to watch up several episodes. I'm much more consistent with watching the stuff Yahtzee does on his youtube channel with Gabriel Morton, because it's much more interesting.
Edit: ZP is also what lead me to discover this site, it's part of why I stick around, but mostly because it seems like the only constant here. Well aside from the forums, which I lurked around more than participated in for years, so there is that.
