The Bioshock collection doesn’t use UE4. It uses a modified version of UE2, with some further modification by the team that remastered it.
As for games that actually do use UE4 that are pretty good?
- Player Unknown’s Battlegrounds
- What Remains of Edith Finch
- Unreal Tournament 4
- The Turing Test
- The Solus Project
- SQUAD
