I do feel so harsh for not voting for the other 8 mods, the quality is just so high.
Bathurst Legends - awesome fun with these, excellent balancing and variation with the three models.
F1 71 - more olden time fun, oversteer =
F1 85 - sheer number of models and the sounds are glorious in patches
F1 91 - worth the download just for the sound, but the sttention to detail in the physics is exemplary
F1 93 - best F1 mod out there for reaction to physics and beautiful models.
Armaroli - didn't cut it too much for me, but I can appreciate the high level of polish and RealFeel support
FSONE - yes it took them a long time, but it was worth the wait wasn't it? Stunning models and skins and handling with both depth and accessibility. Couple of sound gremlins and graphical bugs but it got my vote.
GP2 - mucho fun, huge variety of skins
NAGT - probably the best rFactor mod out there when it comes to physics and punishing overdriving
Touring Masters - well I couldn't possibly comment
