I played RF1 during several years. One pleasure was adapting mods to my taste. For instance, in each winter I was doing my own 2.4hrs of Daytona. For that, I was mixing several mods, modifying talent files, damage files, sometimes changing engines, tires data, etc... to make something realistic in term of classes, BOP, numbers of DNF, agressivity, etc. Time consuming but not so complexe. Architecture was easy to understand even for not talented guy as me. At the end it's rewarding to adapt game to my taste. I bought RF2 1 year ago but didn't use it so much. At same time I discovered iRacing and its easy plug and play system. For my off line races, I went to GSCE. Same architecture as Rfactor, some mods, some good circuits. With recent switch to Steam and release of GT3 mod, I decided to give RF2 a new try. I enjoyed. But yesterday I intented to mix URD PX and GT + GT3 Simtek to make my own PLM. RF2 became my worst a nightmare. I spent more than 4 hours for nothing. For nothing! Except make me think I must be totally dumb. 1) Real life skins made for URD (stored in userdata/settings) didn't appear as possible choices when I wanted to make rfmod. I couldn't find way to make them appear. 2) Ok, let use fantasy skins in my rfmod. Impossible to finalize any rfmod while it's supposed to be a standard process. The "light" remained red and I never found solution, even after reading tons of forums. It was writen as installed but in parallel it wasn't installed. Why it didn't work with me? I never understood. Maybe rfm localization or something like that. 3) Ok, let chose opponents directly in game. At least anyone can do it. Perfect, I can chose real skins. But I'm obliged to keep fantasy ones! I don't want them. 4) So, after realizing useful files were stored in "installed" folder I tried to modify mas files to remove official fantasy skins. I couldn't find way. Finally I resigned and opened AMS. Road Atlanta is really well done and make think Reiza products are now almost at same level as RF2 in term of appearence. In few minutes I could find way to make some mods work together. Of course I must do several adjustments but at least I understood how to proceed. RF2 is for sure a good sim. It's supposed to be the best platform for modders. It's probably perfect for hardcore modders who have their own language and logic, but not silly Sunday tuners as me. So, I'll stay away for a while and hope future development direction will go to a more friendly interface.
