I can't remember a single Blues poster saying that they didn't love Plants versus Zombies. I really don't remember anyone even bagging on Peggle, as simple as it is. I think you might have been partaking in some revisionist history. PvZ was almost universally praised here from its release. I know I was hopelessly addicted to it for weeks.
I hated Plants v Zombies. It seemed like such a dumb implementation of Tower Defense.
Peggle was ok, for a game of stupid chance.
But yeah, I think PopCap got bagged on here pretty regularly around 10 years ago. It got the same loathing we give anything else new and getting attention that we therefore don't understand and fear. "Who plays flash games? Oh my god, these idiots. I hope PopCap dies in a fire. Brotard ADHD crap. This isn't real gaming. Look at those sheep."
