Don’t listen to the NIBNEWBS and their propaganda about “code” and what’s “good for the home”. They’re full of shit. The beauty of pinball is that it’s always different. You can play the same game a thousand times and always learn something new, achieve something unique and satisfying, and have fun over and over on the same machine. The 90’s games are generally masterpieces of gameplay, design and rules. None of them are “shallow” unless you’re playing an early DE like BTTF.
If you can score any 90’s game for $3k, go for it...it’ll bring you endless fun. If it ever gets “too easy”, you can always change posts & settings to up the challenge.
