Another vote for the Rush series here. My dad was/is an operator so I spent a lot of time playing various racers growing up. The cruisin series sucks for owning IMO, Rush is a lot more fun. Some of the sega racers are decent too but Rush blows everything else out of the water IMO. Theres also the Thunder series which is pretty fun and worth looking into as well. Offroad Thunder being my personal fave there.
