Since Dirt 5 doesn't have rally mode and you want some arcade racing, you can have this one, Dirt 4.
This game for me feels like sim-arcade to me. You can switch simulation or gamer style.
I personally love play rally mode. Even after I complete all rally mode, I still play competitive mode which is compete time with other player. I kinda want to complete rally cross and land rush, but both of them doesn't make me interested. I prefer play rally cross on Dirt Rally and prefer play land rush on Dirt 2.
Maybe it doesn't have best physic like Dirt Rally or 2.0, but it's very fun game for someone who doesn't pro at rally/off-road race game.
