You get the game you want. The devs do what they intend.
GT Sport is not meant to be a sim. Don't judge it as one. It does exactly as intended - to be car p0rn.
PC2 is meant to be a sim. On PS4 they have failed pretty badly. It needed months more work to get right (in fact my suspicion is, it was never written for PS4 at all and was simply ported across from the PC in a rush, hence all the problems)
I recall a certain slogan... "The Real Driving Simulator" ... in fact, I'm pretty sure its plastered right on the front of the game case? doesn't seem to say "The Real Car P0rn" although i didn't read the fine print on the cover.. Also i didn't see the announcement from Polyphony about it not aiming to be simulator anymore and simply focusing on aesthetics. Its my opinion man, I simply believe that it is GTsport that missed the mark, i was hoping for something a little more realistic, and i understand their angle to appeal to the masses, just unfortunate seeing as the online optimization could have been remarkable for league play/expansion etc. However, the game feels like i'm driving with a wet noodle in my hands rather than a wheel, so its just not worth it IMO.
I also don't feel like PC2 was a "let down" ... i do feel like they did miss their marks on a couple of areas, however overall the game is pretty great once you get it set up right (as annoying as it is). FFB took some tweaking, but i know have it where i feel its as close to AC as it is going to get, and the physics are pretty damn good (after 2.0) although yes, glitches and issues are still prevalent (oversteer glitch, DPS). However, these are manageable, as you cant get as immersive as an experience (on console) with any other sim out there, so id say its definitely worth it, again, IMO. On top of that, remember where PC1 was when it was released?? Imagine what PC2 will be like in 6-8 months, i know that's ridiculous as we paid good money for the game now, but hey, optimism is in the thread title. We got what we got, and its really not bad (IMO), so i think we should just continue reporting the issues we have so that they will be resolved and this sim can get to the glory we all want it to be!
