I’m gonna be honest. It didn’t matter to them at the time. Look at it. They made their game and we all played it and loved it. For that time they were on cloud nine. They definitely got what they wanted, for a moment anyway. I can’t say I wouldn’t end up in the same situation if I was ever more than a shit dev.

Edit: but to add, I’d put huge banners in game saying it was a requirement at login. As far as I know I was never bothered in game for it. And if I was it was too easy to click and ignore.
