Not as intense as traitors but another great british game show is "Would I lie to you" (you're going to tell me now that you are british and that's it silly to explain it like a foreign concept, lol). The only other thing i remember watching that's competative in the same way as traitors is Race Across The World.

Some Anime shows I've loved: Romantic Killer (Netflix), The Disastrous Life of Saiki K* (was on netflix for a good while). Witch Watch is an okay anime i watched recently, sadly feels a bit unfinished but it's just that new.

• Would definitely recommend SpyXFamily - it appeals to all age groups - but I'm guessing you will have watched that.

Random reccommendations just because they're so good:

• Dropout TV, which is full of comedy and gameshows. (You can get a taste for it from their YouTube channel)
• Daredevil S1-3 (Disney+)
• Deutschland '83,'86,'89. (was on channel 4 iPlayer, don't know where else) & Slow Horses (Apple TV)
