You might find the monthly IOS threads useful; also I made this thread listing 100+ of 2015's best mobile games. I'll be doing another for 2016 at the end of the year
Really strong year. I somehow missed the voting but for the most part agree with this list. I think 2015 was the year where I played more mobile games than console/PC.
