PSX version of High Stakes misses quite a lot compared to PC version. There’s no cockpit view. The weather effects are almost non existing. Just 4 leagues and no modes besides Tournament. So, it’s a High Stakes without the “High Stakes”.
But it has a few advantages as well. First, lighting is surprisingly better than on PC. Especially lens flares. And upgrades actually make a difference in this version, making it more playable that the brutal PC version.
