Originally I entered Tlou in my top 50 games of all time at nr 20. Currently I feel like it deserves the nr 6 spot, just after SotC. Replaying Tlou on ps4 and playing Left Behind and recently Uncharted 4 have only made me more appreciative of what Tlou achieved. It's not perfect yet to me Tlou really is greater than the sum of its parts.
It's probably better if there is no sequel for fear it will disappoint or worse taint all the speculations from the original. However Left Behind was excellent so who knows.
