It looks good. Nice variety of vehicles, especially some of the newer models. I'm not a fan of the PI/upgrade system or the whole early access / VIP / deluxe version releases (the whole industry is headed that way, if not there already - £70 games are bad enough).
Don't think I've seen enough though, along with the other games in the showcase, to make me buy an Xbox. Not really interested in space stuff like Starfield. Avowed does look good. If they can get xCloud streaming working better I'll probably play it that way. It was just about tolerable playing FH5 on my Mac (via Edge) but I'd much rather play on the TV. Hopefully they get their app working on more devices or release a streaming stick.
