As sad as it is, i think is for the best for nfs, the last truly enjoyable ones were carbon and most wanted, perhaps nitro if you could ignore the aesthetic (i couldn't) but on ps3 onwards the game were just so "meh" there wasn't really anything remarkable about them, nobody really gives a shit about the last 19 years of need for speed and it shows, compare how talked about most wanted, underground 1 and 2, Porsche unleashed, etc, are when compared to the likes of rivals (not the psp one) or most wanted (2012), heck, the "more interesting" one in the last 15 years was on the run, and it was because of the abundance of cutscenes and quick time events, nothing else.
As for burnout...yeah, it's extremely disappointing, but can't get really frustrated or angry when the series hasn't had a game in almost 20 years.
Rest in Peace.
