You keep neglecting everything PD was doing WHILE developing GT5 that wasn't game related, and they never grew the company nor outsourced the work. That's resource mismanagement and taking on way more which affected PD's core business. Like mentioned, it's mostly PD's fault to blame for how GT5 was released and patched up. Very ambitious game for sure but the bulk of content are lower quality ports, from the cars to the tracks.
Based on FM2 and FM3, T10 will add more cars and tracks. FM2 saw 2 DLC tracks and a few car packs whereas FM3 saw 1 track pack and roughly 10 car packs (they missed a month for their 1DLC/month claim). There's the rivals mode which has monthly community based events as well as T10's own community driven racing events (from paint competitions to racing to photo events, and they've already done some of these only 6 weeks since launch.)
I just hope that T10 doesn't go on a year from now releasing an Ultimate Collector's Edition with exclusive content for this like they did with the FM3UC. 🤬
It is a heavy car in real life but I think PD got it completely wrong in terms of the data and performance. Based on Stig's Top Gear lap time with it, so take it for what it is, it's 12th fastest of all cars tested. The way it drives in GT5 is a heavy pig that can't turn for the life of it.
The Prius is crap, overhyped, purchased vehicle by the blinded faithful who were milked lies thinking they are doing this planet a great service. There is no racing pedigree with it and the only thing it does in terms of performance is good fuel economy (not the 80mpg that Toyota claims). And PD charged you money racemods of existing cars where the Prius was one of them in their last DLC
