Two initially jump to mind for me.
Outer Wilds took me three attempts to get into, but when it did…wow. Its a game that I is definitely more than the sum of it’s parts, and one that I’d argue is genuinely beautiful in it’s story and how it tells that story.
That said, once you’ve worked out the games mystery; it’s story, it’s tricks, timing and logistics, I wonder how more pull the game would have.
Return of the Obra Dinn is a game that I spend a lot of my time thinking about. The music, the atmosphere and of course, the games moment to moment gameplay.
Those puzzles will likely (hopefully) melt from my mind at some point, but even then I fear that initial sense of excitement and intrigue will be lost.
As much as I plan on going back to it at some point, I’m not sure a game of it’s nature is all that well suited to additional playthroughs unfortunately.
Dayz.
There is no other game that has ever given me the same adrenaline rush as Dayz. It just hits different. The learning curve is a bit steep, but every step and every player encounter is a memory to remember. Really wish I was less experienced and not knowing the maps inside out, really wanting to get lost again not knowing might what happen next.
The game has come really far and more players are playing it now than ever. The game has great modding support and community servers. If you have never experienced Dayz then you really should give it a try as it is often on sale.
But remember: no mic, no life.
