Well, that's exactly my point. I don't understand why you said 'what could they possibly do with this series to make it interesting again?' when you have games like Gran Turismo with much less variety and people are still loving them. - Maybe I misinterpreted your meaning?
Okay, what I'm seeing here is that you are taking what Amer said by the literal definition of each word and not the meaning of his statement itself.
Gran Turismo has offered a consistent an evolving experience to it's games. GT would follow a theme, and continue adding to that experience. Where has NFS done this? I can't think of one game since high stakes, that really ADDED to the experience of Driving supercars, customizing them and out running police chases, with cockpit view, semi-realistic handling etc. Since high stakes.
NFS 6 was a down grade, (Sorry guys, it's true, NFS high stakes had more gameplay than nfs 6 )
NFS underground was a different theme, done away with supercars, bringing on the crowd saying "oh you can't ever have super cars racing with suped up street cars" Wanting two seperate themes.
NFS underground 2 added to the customization, but we lost so much of the pure NFS experience. In the underground series.
Okay here comes most wanted, which has been arguably the best NFS in a long time since HS. What did it really offer though? HS with an open world, (SORT OF) but we lost the semi-realistic handling, and the cockpit view.
Carbon was just a rehashed most wanted, didn't offer much of anything new. Undercover was a cruel joke. NFS HP 2010 offered no upgrade to the experience of driving a super car in an intense high-octane situation.
It took away the skill and replaced with drift, yet HP 2010 was one of the best NFS games infact still is in my opinion the best of the 2010x series of NFS. But still, it took away the authenticity that NFS 1-4 had, as well as the customization. Same for NFS 2012. 2013 brought back some customization but took away some of the greatness that 2010 had, the physics are even more of a pain in the ass.
NFS World was just an amalgamation of nfs most wanted and carbon, with degraded content and too many things locked behind a paywall, the game continuously got worse and worse.
NFS 2015. Took even more away from the series as far as customization goes. Very limited in how you set up your car if you want it to control right, and the lack of parts, neon, etc. Most wanted had MORE customization than this game!!! and better car physics too! better police chases too!!!
Look at this, you can't tell me I'm wrong because the proof is in the pudding. Forza/GT add to their core of the game, and providing a consistent and evolving experience with each new entry in their respective franchises. Where does this leave NFS? Dead in the water. I still have yet to play an NFS that surpasses High stakes.
NFS is nothing consistent, and nothing great anymore, and that is a very SEVERE problem.
