I can vouch for Fez; that games is insanely impressing and even ignoring how amazing the secrets and its world are, the platforming and puzzles themselves are pretty interesting and fun on their own right. It's an outstanding game and I really hope you play it soon :D

The Dick McNugget dynasty is one to be proud of...

Love seing this 'cause creating custom cahracters and using them in different games is probably one of the funniest things ever for me, like creating the third Mario brother called Maurice in Smash Bros as a dumb joke and ending up using him as the main character in my Miitopia playthrough or building up entire family tree lines with some friends through our characters in GTA Online and Red Dead Online...

But probably my favorite I've ever done is making Count Lemongrab from Adventure Time in Dark Souls 3 and then using himin both DS2 and Elden Ring; there's something so funny to me about that menace of a being just showing up as an Ashen One and imagining him screaming *UNACCEPTABLE! at bosses; he and the way he looks clash compeltely with the rest of the world and that somehow makes him fit even more. I know he isn't really a ''Custom Character'' since he isn't completely original, but still, he's my favorite by far and when I finally replay DS1 I'll eb sure to also make him on there xD
