I don't like MMOs. You know these games: World of Warcraft; Diablo; Lord of the Rings Online. I don't like them because they're boring - they're safe.
The combat is all based around maths and stat points. Rather than feeling like you're in a genuine fight, you slowly grind down an enemy's health meter while spamming hotkeys to top up your own. The missions or quests are similarly dry. Typically they involve collecting X amount of MacGuffins, or venturing into some cave to kill a few enemies and collect a bunch of treasure. Worst of all, the majority of MMOs all run with the same aesthetic; the same sub-Tolkien, elves, dwarves, and magic narrative setup.
