I will agree with everything except for this, I have own both systems and I play a lot FM and GT on both both of them, and there are things that makes FM3 utterly boring, which is the same stuff that is being brought back to FM4.
With this I have to mention the Career mode and the game in general, for people who play just the demo and haven't play the full releases(FM2-FM3) it should be acknowledged some things like the lack of arcade mode options on FM3(just car and track, no difficulty or race settings), the huge chunks of grind that composes the career mode and the redundant use of the same cars on the same races in career mode.
There is an Arcade mode with just you and a track. Called Free Play. Also I got from 1-50 in a matter of a month by racing onlineoffline and not using the same car from different race series. Maybe a grind to some...not like GT5 grinds though.
These things are the sort of thing that take FM players out of the game, and the sort of things that really make the game boring, you can tune the cars and do plenty of stuff on them, but is rather repetitive when you have to race the same cars almost all the time. For the variety that FM provides there is very little variety on the events, the online modes are not similar to previous games like FM2 in which tournaments and hot lapping competitions were organized, the unlimited use of rewind(finally regulated on FM4) makes the game more arcadi-ish in the sense that people do not race carefully making the psychological pressure absent from the driving aspects of the game.
Thats just not true at all. Rewind never has to be used, I never used it. But saying it makes it arcade is just as silly as taking an overpowered car to an A Spec event in GT5. Like an outrun game. Same concept. Both CAN be done...but dont have to be used.
But the main problem with it is the driving assists which are still present, even for FM4, they not as aggressive but they stiff affect the driving characteristics of each car, for example the Zonda is not as aggressive when you apply full throttle after a corner, and that spoils the experience for hard core drivers (what makes it worst is the fact that FM2 did not had assist involved, and it actually punishes you for getting over the line with cars like for example the Corvette). These problems are simple, yet significant experience spoilers, just like the annoyances present GT5, these problems can be acknowledged by T10 but they are not attended or fixed, instead the resources are redirected to appeal more to the mainstream market, which is not a punishable thing but it is incorrect when such focus affects the experience for more experimented players.
You do know that the steering glitch is only when using 900 degree wheels right? And that T10 are aware and fixing it right? So there will be no steering assist.
To get back on topic I get rid of GT5 because of similar problems, the variety of events was there but the levelling out systems were atrocious, the limited mount of premium cars is always problematic and glitches that are unacceptable, the AI is plain static in the sense that its not aggressive or competitive (something that even NFS Hot pursuit does), B-spec is a massive waste of time, and globally the game is plagued graphical errors, the track editor is extremely limited and the damage model is a really bad joke.
Even with the announcement of spec II I don't think I'm getting back to GT5 either, because that update do not fix the broken career, because having 1000 cars with GTPSP cockpit is not the same as having 1000 premiums. I might get back to it if they announce Spa with 24 hours cycle and weather, but I know that is something that is not going to happen.
My point with this is that people should try before buy, and people should try before judge, is logical to assume that what you like is what many people like, but sometimes that is simply not the case, and I personally rather expend 60USD on MW3 than on FM4, because I know that I wont play FM4 that much, as many people seem to do when you check the online servers of FM3.
