Project Zomboid, even though I'm not into zombie lore.
- Isometric perspective graphics, one of my favorite game perspectives
- Open world, open-ended, sandbox play with enough of a game objective to not be boring
- Hardcore survival with deep, often surprising mechanics
- Amazing multiplayer experiences
- Loads of suspense and tension
- Constant development from a small, totally independent team
- Incredible array of community mods
I would love to see other games in the same vein using other scenarios besides zombies, like maybe warzone survival, etc.
