EverQuest Legends™ (EQL) is a newly reimagined version of classic EverQuest from its original release in 1999. Featuring all the fun magic and nostalgia of the original game, EQL is also packed with tons of new features and quality of life enhancements.

So it's basically a Remake of EverQuest. Not sure how this is comparable to WoW Classic or even Old School RuneScape classic, which are not Remakes, but an earlier state of the game.

EQL has been designed from the ground up to appeal to players who enjoy playing their games solo and/or casually. While groups (up to 4 players) and raids (up to 8 players) are available, the entire game can be played, enjoyed, and experienced solo if that’s your playstyle.

That's good. My only problem with these kind of games is, you have to pay a monthly subscription.
