As a kid I had to choose between FFXI and Star Wars Galaxies - and then Planetside came out!
I had a lot of good times in those games but switching between them month to month because I could only afford one at a time gave me a pretty healthy aversion to subscriptions before I got out of middle school. The only subscription service I've ever had was YouTube Red when it first came out because I was interested in a couple of the shows, but they all sucked so now I'm back down to just one subscription (FF14) unless you count car payments and my cell phone plan.
edit: oh wait I've also subbed to Disco+ for battlebots, but that was only because whoever was uploading them to 1337x stopped doing it which was a shame.
