yeah i have seen people use that before

on *:text:*whosaiditgame*:#:{
if ($1 == %c $+ whosaiditgame) {

i think it's an old way of coding.
even tho in the on text it's set up as a wild card match using the the " if $1 == %c $+ whosaiditgame " will make it only trigger if it's the first thing said like using

 on *:text:whosaiditgame *:#:{

to me that extra if line is a waste of space tbh
