IIRC new gambling laws have made the gambling den thing at the first Rocket base illegal in many countries as slot gaming is +18 only.

I'd sooner they just release the original GB clients in countries where it is legal and have them be as-is. If they did a full remake people would moan about all the grinding required to build a decent team--at least everyone did that for the first Switch gen (name slipping, one with the rich guy using legendary to power the country). Same with SMB. So much of the game relied on predicting enemy movement, your speed, and timing jumps. If ANY of that doesnt translate onto a new engine (which it likely won't perfectly), people would get mad.

More often than not remakes and remasters really compromise the original.
