I personally think NFS II, High Stakes and Porsche Unleashed were very good games, and I think most people here agree with this. It's the more recent 'zomg rac0rz lolwoo1337!11oneleven" that I have a problem with. The original Underground (was it the 6th?) wasn't too bad, but seriously, does it need to be reworked ten times? I don't even know what's the NFS count now: is it like 12?
Don't get me wrong, I'm not entirely against the whole mod thing. It could be a good thing, but is it not because it is presented to the customers as 100% 12 year old arcade material. It is in no way representing the real world of modding, which we don't even know what is really like because it's been represented in movies as content 12 year olds would like (which they do). Now, if somebody bothered to release a serious modding simulation game, with content designed for people older than 12, something interesting might be achieved.
The only problem with modding is that it has been worked by crappy movies and video games into a stereotype of a ludicrous world, and most importantly, arcade type racing, even in the movies (let's go fly over some buses with our 12 feet high winged japanese cars, aye?).
So no, we do not want LFS to become just like NFS, because we like our older audience, and the level of simulation we have.
