Bring Back Live Selection
The biggest issue with Resident Evil 3’s campaign isn’t necessarily the short length (most RE games are short), but the cut content. One of the key defining features of the original RE3 was the live selection feature, where you could make choices at various points in the story, and things would play out a little differently.
For instance, early on in the original game when Jill encountered Nemesis outside the RPD, she could choose to fight him or run away. While this never affected the story in a big way, it did still provide some variety to the overall gameplay experience.
If it was implemented in the remake, it certainly would’ve added to the game’s replay value, and give more players incentive to return to it over and over again, rather than just the hardcore fans.
Instead, that feature is completely cut out in favor of a more linear and streamlined campaign. This isn’t a bad thing in and of itself, but it would still be nice to have some small branching routes here and there.
