Metal Gear Solid 4 will always remain that game that ahead of its time and also showcased potential of PS3 around the time
Batman Arkham City was truly spectacular as it really shelled out open world action with its titular character with game play mechanics well nurtured
Bloodborne really helped me to get into souls like game. It actually helped broaden the gamer base for souls like games and still remains as a time-less exclusive on PS4
Need for Speed 2015 was exactly ahead of its time. Cars had a lot of tuning stuff that gamers slept on.

For me, Metroid Prime is another one that feels like a game way more modern than it is, with its insane attention to detail and immersion, how perfect and grounded stuff like traversal and the camera feel, and the fact it all flies by at a perfect 60fps.

Back in the day, it felt like playing a game from the future.
