If you are talking about classic NFS, that will be something like The The Need for Speed, original Hot Pursuit and High Stakes. Underground was never part of the older NFS and it is no longer feasible to make an Underground as putting neons and bumpers on cars are no longer the fashion these days. And it look stupid on cars these days.
Then, EA asked Criterion to make NFS games, instead keep making more Burnout games, while let the excellent SMS go to develop Project CARS on their own as an independent company. Black Box wont make any more retail NFS, but they will focus on the stupidly expensive MMO. Yea, i am still playing cause i have tonnes of Boost from January's cheap sale. If you dont have a tonne of Boost, just ignore NFS World because the whole game is a rip off. I still want my RM100 back for those Boost.
They need a new studio to take over the NFS series with something interesting and new, instead of rehashing Burnout with licensed skins or making terrible games like The Run. EA do have a few good racing game studio, which is the studio who made NFS Nitro and also Firemint who made Real Racing 2 on iOS. I just hope EA will give them the chance to build a proper NFS.
I desperately wants to see the new Most Wanted succeed, because i loved Black Box's Most Wanted but from the looks of it, it's like a burnout paradise reskin with licensed cars. It could be good at the end, but i really doubt so as Criterion seem to focus a lot on the multplayer side of things. The single player is probably gonna be terrible, similar to Hot Pursuit 2010.
Oh wait, since when EA dont butcher their games? Dead Space 3 becoming a Lost Planet clone. Mass Effect 3 becoming a Gears of War with a crappy Horde mode. Battlefield 3 becoming a CoD clone where everyone prefer to cramp in the subway throwing grenades. Dragon Age 2 becoming a rubbish game. Instead of making something original, at least what other major publishers tried to even though they milk the crap out of it, EA decided to just copy their competitor's product and call it a day. EA seems like they just dont want to make a compelling single player games anymore.
