I agree with Meza994's sentiment although it is probably more sim oriented than what Codie's F1 games are but yes, the development system needs a huge revamp as the cars slowly becoming awful to drive during season 2 and beyond is tiresome and unrealistic. Hoping for a positive change in F1 23 but won't hold my breath.
I've banged on in the past few years about customisation, customisation, customisation, there just isn't enough in these games. You do 1 career mode playthrough, you've done them all...
Driver Retirements: On/Off - I personally would have enjoyed an option to have Kimi, Seb and Fernando in previous games without retiring in season 1 or 2 every time. It'll be disappointing if Fernando announces his retirement like clockwork in season 1 in 23.
Rearrange order of GP's - No issue with there being an Official order to keep sponsors or whoever happy but there should also be an option in a video game for players to choose their own GP order. There were rumours of this being in 23 but we'll see, I can't see it personally.
GP Format - like with Grand Prix mode in 22, I would like the option to be able to remove sprint format weekends altogether especially after the horrendous DQ and tire strategy for the following race bugs that ruined 22's career mode.
MyTeam coop career - This one is obvious, shouldn't be too difficult to implement and needs to happen.
Finally, the big one for me is mod support for coop careers, private lobbies/leagues. This community has some amazing modders which are sadly limited to single player modes only, adding mod support (removing online services check) to before mentioned areas of the game would add amazing life to the games and most importantly how players view and interact with them which is sorely needed after the dumpster fire that was F1 22.
If the rumoured new game engine for F1 24 is correct, this will be a huge moment for Codemasters to make really positive changes and win over the player base.
