I don’t totally agree with your point about improving the original Bubble Bobble and R-Type as those were games we paid for back in the day, and some of these developers may be doing it to make the games they wish that they’d bought back then!
There’s two good points here. I want to play games created by people who have the passion to want to make games (which includes conversions of old games as well as new games). Contrary to that, I don’t want really to play a game, no matter how good it is, when it’s been made purely by prompting AI. As @Ivan_Avila said in another topic:
For me, playing games is also a hobby, I’d rather experience games created by someone who has put their passion into it.
That’s not to take away from anyone who is happy to play AI-created games, that’s fine, enjoy yourself.
