There are roughly 50-70 new games released on Steam every day. I think there's pretty good review metrics available that you can assume 2-5% of those could be categorized as "Excellent". So that's around 1–3 excellent new games per day on just one platform.
Even if we're over-estimating "excellent" by a lot, that's still more games that anyone can reasonably play.
