Can I leave Games and Tournament completely cause the topic is not being asked in CAT for long time

I guess Yes, as its questions also are damn time-consuming.

Hi Games and Tournaments is an important topic with respect to CAT and in DILR from past few years there have been sets which involve concepts from all the topics so even though a pure G&T hasn't come since last two years but its application has been used a lot in many sets in CAT 2019 as well as CAT 2020.
