Gamer's block - is it just the game or is it a general thing ?

I'll start off by saying that I'm a massive MMO fan, so I've played since I was like 8 years old – Mu Online, Maple Story, FlyFF etc…

I always wanted to play WoW but didn't want to play the fee so I played the demo or on my brother's account and that was it, until 3 years ago when I realized there are PS so I joined one and had some fun, played with a team for a few months until they all quit and so I quit with them…

Fast forward to about a few months ago, I re-downloaded the game (same PS) and played with my girlfriend, it was great for about a month, and when we couldn't play together I played on another character to avoid out-leveling her and I burned myself out, however I did still enjoy the game and added addons to increase immersion, disabled the minimap and quest markers and only relied on quest text to find my quests which all really helped immerse me and make me enjoy the game more.

As I progressed I felt like I didn't know the story enough so I decided to check out how to learn the lore of Warcraft and I found YouTube to help quite a bit but it wasn't immersive enough, I wanted to PLAY the lore and learn it that way – hence leading me to go back and try Warcraft 1 : Orcs and Humans despite never playing the RTS genre, I started to enjoy learning it and after a few weeks managed to complete it (it was a PAIN)
Then I went on to Warcraft 2, and made it to about 70% before feeling like I can't pick it up anymore for the last 2 weeks, but also leading me to drop WoW and another game I started playing "Enshrouded" to try to re-kindle my love for gaming…
