The Codemasters F1 games are not addictive at all for me. For me I wished codemaster hadn't got the license to make the game. Codemasters are excellent at rally games and excellent at rally physics...but I have a few gripes with their style of making games. (anybody remember micromachines back in the ninety's?)...
Codemaster's games are long and drawn out. In otherwords the "work and time invested" to fun ratio is very poor.
The graphics are too glum and brownish looking, the sunlight (is there even sunlight in this game?) doesn't look good. Just depressing.
The tracks feel narrow for some reason too.
Physics are Good, but the game doesn't make driving an F1 feel as fun as it should feel.
I preferred how the Formula 1 cars in Gran Turismo felt. They really felt like they were glued to the track and you could push. I have a game pad, and the biggest issue for me is how the steering is mapped to the joystick. The deadzone is too big and there feel is not progressive. I don't have a steering wheel, but gamepads are what most of the buyers are gonna use.
Overall, i still play the games, but not for fun from the game itself... I only play them before Grand Prix weekends to learn the tracks so that when I watch the F1 on my sky Subscription
I know how the turns feel like to the drivers. Makes viewing F1 a little more satisfying.
