Doing barebones ports when emulation is available is an enormous waste of resources. Frank Cifaldi's GDC presentations do a far better job than I could to approach this issue, but devs and platform holders should embrace emulation as a cheap, easy way to keep games in circulation. The PS2 games on PS4 could've been great but they're a complete wasted opportunity since they mandate trophy support. That increases the cost, which increases the amount they charge. People don't want to pay an inflated cost for tacked on trophies when emulation is already so easy and free, so they don't sell enough to justify the cost of the program. Either barebones emulation or more lavish presentation would do, but they went with the worst of both. I think Nintendo's efforts on Switch are great, but more games would be even better.
