Glad you're impressed
There's absolutely nothing wrong with them adding better games of course - and I prefer when they do - but part of me is happy when I don't see a game I don't immediately want to play.
A big reason is because the nature of game pass is ephemeral and they don't always keep the ones I
do want to play. As an example, I'm still worried they'll take A Plague Tale off because it's been up for ages and I've not yet got around to it. Part of this service does mean having to prioritise, which is admittedly both a flaw and positive thing (dependent on how you see it).
Thankfully the adds have been a bit crap in recent months so I haven't had to worry so much
