What a nice surprise!!!
Cruisin'my libray I stumbled upon this hidden gem of a game and I can safely say that ever since Wave Race 64, or arcade racers of the early 00s like Hydro Thunder, I hadn't played anything like this.
Unlike those great gems of old, Riptide GP2 offers a deep career with both pilot and vehicle upgrades, you can also purchase new jet bikes and customize them. Music is just great, reminiscing of Wipeout or Motorhead, sounds, while basic, do their job. Graphics are up to modern standards with the reflections on the water being very realistic and bike handling at the very least obeys basic water physics.
If you have played those classics I mentioned, then you know what this is about and there is no excuse for you to not have this, if you don't, hey, it's not that expensive, jump in, the waters are great.
