For me, one qualifier for whether or not a game can endure is how well it holds up against modern games when it comes to how fun it is to play. For example, when I compare Deus Ex to Human Revolution, the game feels uncomfortable - the reason is because gameplay and graphics have advanced to the point that Deus Ex starts to become tarnished with age.
On the other hand, DOOM is far superior to DOOM 3 in my opinion. Part of this has to do with the genre shift of the latter game, which makes it harder for me to recognize it as a Doom game. While both games are technically shooters, they are completely different. DOOM is credibly fast-paced, and has a level design that doesn't adhere to reality. This is incredibly important, because the designers can create levels with gameplay in mind. They carefully place monsters and build stages that are designed with keeping the player interested in the game. Most shooters have me feel like as if I am stuck in a box, but DOOM goes the extra mile and makes that into a puzzle box.
There is a ton of things that go into making a game endure, so here is a cliff-notes edition of my opinion:
*Aesthetics are more important than graphical power, as they resist aging.
*Simple controls are critical to making the player become immersed.
*Good writing stays that way.
*A strong melody is key to making game music memorable.
*Games should offer gameplay that is easy to learn, but difficult to master.
A quick list of games that reflect my opinion:
*Legend of Zelda: Majora's Mask
*Tetris
*Super Mario Brothers
*Final Fantasy VI
*DOOM
*Castle of the Winds
*Phoenix Wright
*Sonic 3 & Knuckles
*Advance Wars
*Katamari Damacy
*X-COM: Enemy Unknown
