rFactor reviews and comments

thrustmaster f150 is recognized only displaces the game every time the pedals and then you have to adjust the every time. I haven't had anything like that at any race game

A slightly older but also a very good Racing Game with a huge Number of Mods (track/vehicles etc.) I pers. Play rFactor very happily and give this Game the full Score.

Please bring a Steam Works-op for Mods, as with rFactor2. Don't Want to Install the Mods manually, only crashes at all times, better with Workshop, as there is no more Crash. I hope there are even more Fans of rFactor who would like the same as me. Thank you very much

Excellent game which we can put hundreds of mods (of which this is huge) but I regret that the rain is not present in the game and also that IA behaves quite strangely (in my mod F1 1998 at the Estoril circuit, the AI takes the vibrator of the first round and crashes voila)

Still good after all these years. Game looks dated visually by now but if you're into mods you'll be served. Plays surprisingly good with a gamepad but the experience is better of course if you've got a decent wheel. If you got a low spec PC and is searching for a simulation this might be the racing game for you.

So rFactor is a good Simulation there are many Pro's And actually no Contras in my Opinion the damage model is pretty good even if a Car part is lying on the Track and there is driving through the Car broken there are many tools where you can make your own Hod and s A dedicated Routes the tools are quite hard to make at least the Track itself there are many good Mods and good Tracks and a lot of them I find rFactor very realistic you do almost everything on its own but also use Help as I recommend everyone rFactor and not this F1 from Codemasters which is Unrealistic I hope I could help everyone a lot of fun with the Game

In itself rFactor is very good of the Sense and what you can do with it, the Problem is that the Game itself is not the Game, but the Game consists rather of the Mods. That'S why I rate the Mods, Possibilities and the Game! But What can be said is that the Mods are very big, but in The End You get a whole Game per Mod! The Possibilities, not only the Variations of the Number of Racing Silicers, but also what you can do then, E.g. Racing Leagues, fun races, etc.! The Game is difficult to judge, graphically the Game is not so bulging, but it goes very clear with "Physics"! Conclusion: Very difficult Game, long Learning Time for Players like me who have never played anything like this before, but that's also quite normal! Graphically not strong, but physics is also the Point that Is decisive here!
