Do you want gameplay tweaks/changes in the BioShock Collection? Or should everything be the same as it was?

With the possibility of seeing a remastered collection this year, I thought it'd be nice to discuss the potentials of what we could see in the three games. Now, I'm not referring to specific unique gameplay elements that each game has; those should be kept to differentiate them from one another. But this is more about the general stuff, the things that are common across all games.

BioShock 1 would be the first thing that come to my mind when I'm talking about this. Now obviously, the features were added in 2 and Infinite because they were developed much, much later on, but there were two things that BioShock 1 limited you in: you have to manually select your melee weapon, and you have to manually change between your normal weapon, and your Plasmids. Obviously, these got changed as soon as BioShock 2 came, but would you like to see those changes implemented in the remastered BioShock 1? Or would you rather they keep it as it was for the integrity of the original gameplay?

Also, if possible, what features from the games would you want to see changed/implemented in the remasters? Let's get some discussion going!
