Of cause wheel racer believe CM SHOULD make the Legend difficulty not for non-wheel players but i do understand if CM refuse to do that even though i am wheel racer too.
Let me put it this way. We cant expect all the game have very high detail graphic just because we using very high end CPU system, i have many friends who still using some at least 4-5 years old GPU + CPU + 2GB ram with some outdate Mobo system, game developer need to take this into account or else those machine will have no chance to run these type of high graphic demanding game & lower the game resolution itself not always help.
I dont know which game is the most graphic demanding game right now (Witcher 2 may be) but i believe many other game developer can make any of their game just like that too if they want but most of them always prefer to find a balance between quality vs performance because not all the player have $$$ to keep on update their system.
Ok now back to F1 AI issue. I believe its just a piece of cake if CM wanna to make their AI become so fast & so smart & claim that Legend difficulty is not for non-wheel racer but guess what, i bet most non-wheel player will not happy because legend AI is impossible to beat, they feel being isolated, start to complain & thinking that CM actually forcing them to buy a wheel
even some wheel racer will complain about Legend AI being too hard also because wheel racer not always mean speed racer.
By the way imo CM wont make massive AI improvement no matter what because if F1 2012 AI is so perfect then what their selling point for F1 2013 ?? Better AI again ?? You know developer always left something to improve for the next one or else their job will become so much harder if the previous one actually so hacking perfect.
So we can reasonably expect some slightly AI improvement in 2012 but thats it. If anyone want more than that then mod is the only way or just wait for the 2013 / 2014 / 2015 ..
