I recently rediscovered GP2 and I’m also loving it! Along with Indycar Racing 2. I used to have problems running them (particularly with my phone, which I often play on). But now I have found Magic DOSBox settings that work, they run like a dream!
Great that you play on original tech.
Finnish YouTuber Ted Meat’s videos might be what you saw. He loves ICR2 and GP2. GP2 particularly represents the feel of the whole F1 ‘weekend’ in a unique way. Both still have active communities which is great, with many mods, extra tracks and carsets available.
It’s amazing how these sims play so well with steering wheel and pedal setups that weren’t invented until decades after the games came out 😀
I don’t have a wheel, but I’m having success with laptop and my old joystick. Virtual joystick on the phone also works, but tough during long races.
With GP2, not having the analogue input of pedals makes accel/braking hard. In fact, without most of the driver aids on I struggle to keep cars on the track! With aids on, it feels a more arcadey experience, but requires input and concentration, but is still exhilarating and great fun.
