Alongside shooting, stealing, and driving away from the police, the Extended Look showed skydiving, wrestling, basketball, working out, and diving. Fishing is mentioned separately with the Squalo.
Trailers show a much wider fleet than the seven vehicles that received a name in the editions, on land, on water, and in the air. Weapons on screen got engravings, tints, and skins. Rockstar publishes a full list of those only with the game.
The full list from the footage: basketball, pool, weightlifting, swimming, scuba diving, kayaking, fishing, hunting, base jumping, parachuting, a shooting range, car and dirt-bike races, jet skis, and fanboats. Electric scooters are around Leonida too.
In the safehouse you can drink, smoke a cigar, or watch TV and flip between channels and ads. Previews also mention mini golf and a zoo, and bars and clubs fill the nightlife.
