Yeah SRL should come back.
Nah I'd rather shoot things instead.
Sparrow Racing League was a fantastic event, a great way to just waste time and play with friends. I’d definitely love to see it come back. In response to your other question, I wouldn’t recommend any mods for them. Last I remembered all the sparrows had the exact same speed as each other. Maybe they should add booster pads, or make the races a little longer than they were before and add some sort of obstacles to the races, that would be cool.
