It's not bad. Shame about the pit lane and lack of groove/skidmarks (and it needs much better optimising for races), but for hot-lapping it's a nice track. I much prefer this layout to Terra 21's recent Long Beach from Forza, this one is just nicer to drive, I think. Less hairpins. Is this one an 'official' ribbon too, just an older/different one? I don't know too much about Long Beach as a track.
The Terra21 forza version is the official layout used by indy and IMSA. The grid one is a fantasy one. Or at least I don't know of any series that raced at that version of Long Beach IRL
