Gran Turismo and Forza Motorsport are both my most dedicated 1st parties of all time

Here are my reasons why these two are my most dedicated 1st party IPs of all time because:

• Having good realistic driving physics for the simcade standards but both definitely not as realistic as higher tier sim racers such as Assetto Corsa, rFactor, GTR (Sector3 Studios), Race (Sector3 Studios), and Project Cars.
• Having a good roster of playable cars and racing circuits.
• Having tons of car upgrades to choose from.
• Nicely designed menu UI.
• Good menu soundtracks.
• Realistic timing in pit stops.
• Decent career mode until the release of GT Sport and Forza Motorsport 7, but I hope both GT7 and Forza Motorsport Reboot will have a better career mode.
• Circuit racing is my cup of tea in realistic racing games in general.
• The driving physics wise for these two, both are more accurate and realistic than Sega GT and Sega's Ferrari F355 Challenge.

Bad things with these two at this moment:

• Rammers in online racing matches are so rude.
• Some cars are absent (Due to licensing expiration).
• Forza Motorsport series still lacks proper pitstop animation.
• GT Sport and Forza Motorsport 7's career mode felt underwhelming compared to previous ones plus lacking qualifying mode before the main race.
