They’re both very cool and have a wide range of WOW Classic TBC Gold applications. I’ve personally liked ESO’s story better, however I’ve played more Elder Scrolls games than I have Final Fantasy games, so I’m familiar with lore and references much more frequently there.
ESO has a smoother housing system than the FFXIV. ESO allows you to tilt and float objects without needing to take advantage of bugs. All instances are in a single instance (but big) meaning you don’t have to fight with other people over plots.
You don’t have to worry about it, it’s still not classic rock. The definition of “classic rock” originally began as simply “rock that’s at least 20 years old” However, that wasn’t the case a few years ago. For a long time, “classic rock” has taken the form of “rock from the 70s, 60s, and perhaps a touch of the 1980s”. Classic rock has a particular sound, that sounds of Jimi Hendrix, Led Zeppelin, Rolling Stones, etc. Nirvana and Metallica don’t possess that sound. Actually, none of Metallica I’m guessing Load and Reload kind of have a bit of that.
My local classic rock station added music from the 1990s including alternative, grunge and mainstream metal. When they did that , they changed their name to “classic rock” and then changed their name to “rock”. The genre tag doesn’t fit their sound anymore, even although it’s still 85% classic rock. They even referred to buy WOW TBC Gold themselves as “classic rock” and “90s rock” for a time.
