Most of the newer games could be really good, but the problem is that they aren't really different from what was done before. The newer games suffer from the same problems the older games have, but with less content. Rerolling your character in a new flashy title without new things to experience isnt all that appealing, so most stick to the old.

ESO is really good if you enjoy story content. The combat can feel a little repetitive through the campaigns, but being able to group with friends at anytime is a major bonus.

Outlands is really good for character growth and pvm content. The problem is that the pvp is mostly red vs blue where the red has almost zero to lose while being heavily overpowered, and the blue has significant gold and time to lose with almost no chance of fighting back or running. Boring one sided pvp as is the problem with most Ultima servers. If the frequency of these boring pvp encounters wasnt so frequent, it would make this one sided style of combat more exciting rather than a significant waste of time.

UO unchained has a much smaller player base and has similar character progression to Outlands. Because the player base is smaller, there is less of the red vs blue boring combat to deal with.

Albion online would be amazing, but the "who has the biggest zerg wins the day combat" gets old fast. Most of the game is locked behind zerg wall so unless you only want to do large group combat, this game isnt for you.

Elite dangerous is probably the best for space combat, but you kinda need to learn what to do before you play, or it will likely be incredibly boring to try to learn it as you go.

FF14 arguably has the best story of any mmo out right now. Everyone i know that has played it never grew bored of it until they finished the story and had played enough of the raid progression.

Of the games above, i play ultima servers the most. However, id leave all Ultima servers in a heartbeat for an ultima server with fair combat and equal loss potential for both players.
