Just Cause 3

Just Cause 3 is an open-world action game from Avalanche Studios. Rico Rodriguez returns to his homeland, the Mediterranean island of Medici, to overthrow a dictator. The map covers over 1,000 km² from sky to seabed, and almost everything in it is built for cheerful chaos.

The main tools are the grappling hook, the parachute and the wingsuit. You hook onto vehicles and enemies, yank them together, glide across the island and wreck bases, statues and towers. Liberating settlements and military sites unlocks new gear and routes into the next regions.

According to HowLongToBeat (via DekuDeals), the story takes about 18.5 hours, with extras about 38, and a full run about 64. At about 2 hours a day (roughly 60 hours), a month covers the story and most of the side content, while 100% is borderline. The game is single-player, so it is fully available under the offline rental.
