As an 8-10 year old, the concept of using stage 1-2 upgrades instead of standalone stage 3 was lost on me. The car’s handling and top speed is hideously, unrealistically good, especially now that I know the optimal way to upgrade performance. I’d never expect a 400hp Skyline IRL to get even close to 350 km/h like you can in U2. Even with Nos it seems pretty far fetched.
I love this game so much. Stage 5 drag races are so much easier and more fun. It’s also a cakewalk to achieve the target Star rating compared to advancing from 3/4.
