Bioshock is a game I replay at least once a year. Having it on PS4 would be great.
I got Bioshock 2 thanks to PS+ and never bought Minerva's Den. Cool game, better combat, but I rank it a bit lower than the original.
I bought Bioshock Infinite on release day and sold it after a few months. I think it was a quite good (but not perfect) game. Fuck the Wraist battles. I will always remember the E3 trailers that promised a much more open-ended game than what we got. Never played the DLC. I would like to change that.
Having all 3 in a single pack would be great. If they update some of the gameplay in the original, it would be even better. Like being able to shoot and use plasmids at the same time. But I hope they don't remove the hacking in OG Bioshock. It's kind of fun, and when you get tired of it, you are swimming in money anyway, so you can just auto-hack everything.
