Honestly, I don’t see the need for a wishlist larger than ~100 games. You likely aren’t going to buy all 100 games. By the time they release or go on sale or whatever reasons you didn’t buy it but instead wishlisted it, you’ll likely have moved on and not feel the same excitement when you see it again. So what’s the point? Why even have a wishlist if it’s not intended for you to actually buy all the things on that wishlist.
