It’s fine if it goes a few dollars over. Note that I really want to play Subnautica and Hollow Knight so don’t suggest to remove those.
Honestly unless you have infinite time in a day before you finish 3 of these games there will be another sale. There is always another sale, and games only get cheaper. I’d buy 3-4, play those and then look for next sale.
