It is impossibly hard to play games released before 2010.
No idea why those who own the IP don’t just either open source them or release them into the public domain
Because licensing is complicated and likely they are not the sole owners of all technology involved in doing so and there’s no perceived benefit for them to do that unless they feel like they can make money on it somehow.
Because they want to keep it till the very last moment just in case they can make money with a remake or something, even if it crumbles to dust and gets lost forever. What I really want to ask is why does the law enable this?
