6. Jetskis
If I were being picky, and I mean extremely picky, the only flaw in the GTA series would be the horrendous sea transportation. Since Rockstar realised that people could actually swim, there was a focus on how they could develop the world further off coast. We've hardly been blessed with water transportation. We've all been in that position where you somehow find yourself in water, adrift from any land mass. Your only options are to swim (no) or boat jack something (no) or to reload from the last save point. Or drown. The boats are usually slow, heavy and usually worthless, especially when trying to run from the police. You have no hope. Well, GTA V reintroduces the Jet ski. Finally, we'll have something fast and agile to tackle the waves with.
