I bought both AMS2 and ACC,tired them and returned them both. Think I will wait for someday GTR3 to come out. Meanwhile, I have GTR2/RF2 and RRE.
I too bought AMS 2 and ACC now on summer sale. After reading all the comments on bsimracing and here, I thought the was going to be a breakthrough in technology. People are praising AMS for driving experience like we took a 10 year leap in the future in sims, but it was far from what was expected after reading comments. It was far from it.
As for having a little bit time on my hand, I'll add my own 2 cents for AMS now in the paragraphs under, so people could get another opinion on this game. This is neutral as possible since Im not biased towards any sim.
So I own almost all the sims I believe? Everything from 2008 and onwards. GTR2, GTR Evo with all the addons, rfactor, rfactor 2, LFS, Automobilista 1, Assetto Corsa, Project cars 1 and 2, had iRacing for some months. So I've been through it all, I tried both ACC tonight and AMS 2, and refunded them both. Here are my 2 cents.
After reading all the comments for AMS2, with all the praise and fame its getting, I was expecting something really raw and new. Ams looked like a repolished version of rFactor 1, but had a very raw and natural feeling, both driving and FFB. It was nothing like rFactor 1, the feeling of driving the cars was 10 times better than avarage rfactor 1 mods. So I was expecting AMS 2 to be all the best from AC, ACC, rFactor 2 and Pcars 2 combined from all the comments on several sites.
When launched the game and going out the pits, it felt like pcars 2 all over again. same graphics, same style UI, menu, buttons, everything. Even the most annoying feature from pcars 2 was there. You go off the track in the last sector and lose 10 seconds in a spin in the gravel traps, and your lap gets invalidated WITH your next lap, even though you didnt lose time. But anyway, it felt and WAS pcars 2 all over again. The FFB was better, sound, and details on the cars, and characteristics were more raw and better made, but nothing major. I tried 4 different vehicles and classes, 2-3 races and some practice testing. But even with summer sale now, I wanted to have a refund.
The reason is: nothing new or major improvements from the Sim world. It reminded me too much on pcars 2 and come on, the driving experience is great, but nothing "OMFG best experience period".
This is a perfect buy if you dont have pcars 2 from before! This is your answer. If you dont have, go buy AMS 2 right now. But if you've tried everything, you'll find out that this is nothing major new. The best thing in this game are the V8 cars and the Brazilian tracks. I wish all the brazilian tracks would make it to other sims, because they are PERFECT and GREAT! They are the tracks that new sims are missing, you can still have raw racing on them, its the total opposit of Paul Richard HTTT.
ACC was refunded because of its unplayable in VR, all the posts in ACC forum is correct regarding stuttering and the whole bit.
With the money I got back from the refund, Im rather going to invest it on AC paid mods and have fun. AC is delivering great racing with SOL and CSP mods and everything, STILL, after release. So this is rather my cup of tea and my 2 cents, instead of playing around with FFB settings and everything for 2 new sims for 2-3 hours, playing them 5 or more, and going back to 1 sim that can give me everything I want, which is peaking now with quality content and everything, and has most of the issues sorted out.
Again, just my 2 cents and my opinion. Everybody has their own, but I'd rather donate or spend 35 euros on paid mods or private mods in AC, than to "just buy another sim", and buy a premium membership here for online racing.
