I'm mostly into single-player games, and looking to GTS mostly as a museum of motorsports. Scapes photomode, and replays are gorgeous no doubt, but in game is stunning in HDR. I don't understand the negative comments at all. It's HDR done right, and not trying to overwhelm my eyes with how bright the sun is.
Driving School is like a "welcome home" from Gran Turismo. Knocking over green traffic cones with rock music playing gives me a twinge of nostalgia. And the track sector practices really are helpful. Had a fun moment online watching a 3 pack of cars ahead of me who were carrying far too much speed into a corner at Dragon Trail. They predictably binned it, and probably skipped driver training. I know because I smashed into that corner at least two dozen times in Mission Challenges.
Surprised how much I'm actually enjoying online races. Drivers so far have been extremely well behaved. Crashing is slow and lowers SR, simple and effective. Do well by driving well.
I was always going to buy this day 1 and see for myself, regardless of reviews or forum impressions. This demo assures a place for GTS in my home. PD nailed it.
