It’s a great game with great gameplay and which is surprisingly replayable in survival mode if you go a year or two between plays.

It’s also one which, IMHO, doesn’t need visual enhancements - their choice of visual style was masterful (it works and is a lot cheaper in terms of 3D modelling costs that something more realistic would have been) and it’s the gameplay (which is pretty much all emergent gameplay in survival mode with no fixed set-pieces) that makes it a great game.
