Worth or not ? Cause it's the only game with good AI race, safetycar, rain, night, many tracks, complete F1 team without ripped mod, DLSS....and No halo mode, leaderboard for hotlaps....
It is the only complete F1 experience at this time. It depends how much that means to you, and how much 2021 cars specifically mean to you, because F1 2020 does it as well. As a sim racer I would wait for a Halloween sale, by then they'll have fixed most of the launch issues.
