I'd play pCARS 2 if it was gifted to me on PC or especially the PS4. Excluding the laser scanned ones, its circuits are as "bad" as rFactor2's (rF1 is the king of what is bad) but they comport the series available. Plus it has group C cars and two oldies from Le Mans that I'd love to drive. I enjoyed the 787B and 908 in Gran Turismo 4 as they were, for that game. With a gamepad and casual fun in mind, I probably could have a decent time taking those cars through the good circuits.
The pCARS series of games is also a better fit for most of the active rF2 forum users in terms of ability. It's certainly a better fit for the older crowd that also ventured into rF2. Bar the ocean of glitches, bugs and exploits from the last 4 SMS games, it should do well.
