Agreed. I guess it’s that value proposition: if you have the time to play, and you play their whole catalog and have a blast, that’s $16.99 well spent.
As for me I love owning my games (where possible due to licensing and DRM), so the value isn’t there. But my spouse and I certainly took advantage of the heavy discounts they offered like the $1 month. I planned it so that I could try as many games as I could during that period and ended up buying them on GOG or Steam if I really loved them.
If their whole catalog is refreshed and they have another heavily discounted offer for 1 month, I’ll pick up a month just to try those games. But I definitely would never be a long term customer, I’d be a parasite loss-leader lol.
