As much as it saddens me, but yeah TLOU within 2 entries has made a lot. I think they crippled the series by killing Joel, so anything more is kinda a drag. TLOU1+2 are one of my best games of all times, same with Uncharted. Uncharted as well has more wiggle room, but starting fresh with a new IP is always great so when you get back to these titles you feel so refreshed and avoid creative fatigue.
If they announce TLOU3 and Uncharted5 I might tear out of joy, but it's very understandable. Sometimes we don't know what we need until we get it, like moving on from Infamous to Ghost of Tsushima.
