[b]Loot[/b]- Can be obtained in games that are not MMO's so you can't base this as a quality/idea from MMO's. STRIKE 1 [b]Weekly Events[/b]- Occur in games other than MMO's as well. BALL 1 [b]Grouping[/b]- Occurs in all sorts of games, not just MMO's, so can't be considered a quality/idea from MMO's. STRIKE 2 [b]End Game Content (raids)[/b]- That only involve 6 players at a time, NOT MMO. STRIKE 3!! YOU'RE OUT (and by out I mean you're muted after I finish this post) And for shits and giggles lets finish. [b]Social Spaces[/b]- You can't communicate in said social spaces, other than kick balls around. So how is this an idea/quality of an MMO that actually allows you to socialize IN THE SOCIAL SPACE??!!! [b]Emotes[/b]- Don't exist in JUST MMO's so it can't be just considered a quality/idea from MMO's. [b]Character progression[/b]- exists in MOST games NOT just MMO's, so again can't be considered a quality/idea from MMO's Wanna tell me again these "ideas" and "principles" that are from MMO's? Most of what you listed is in all games and are NOT "ideas" and "principles" of MMOs. They are ideas and principles of all games genius.
