5. The Chiliad Challenge
Considering the fabled Mt. Chilliad is set for a return in GTA V, coupled with the presence of another tall mountain known as Mt. Josiah, it would make sense for Rockstar to bring back the side mission known as the "Chilliad Challenge". This was a side quest found in GTA San Andreas that required the player to first build up their cycling skill to 40% and to then commandeer a mountain bike at the summit of Chilliad before hurtling down its steep and rocky slopes alongside other competitors vying to be the first to reach the mountain's base. Sure, going around shooting innocent pedestrians in the street with a sawn-off shotgun is fun, but there was something equally as enjoyable about whizzing down a huge cliff wearing nothing but a pair of shorts to pass the time of day in San Fierro. One of GTA V's main protagonists, Franklin, loves extreme sports such as dirt biking, sky diving and other such high-thrill pastimes, so the Chilliad Challenge would seem to be right up his street.
