Lately I have been pondering this and wondering why I am attracted to certain features in my RPG's I play.
I really had to dig through this as I have played many I like. Yet not too much is common on their themes.
From the old days of RPG's, I am the classic D&D teen. I played it when I was 14 years old. I played the 1st and 2nd edition rules (and briefly in 3.0).
When I started playing PC games, I was trouncing Orcs, Dragons, etc.
Bards Tale, Baldurs Gate, the D&D Gold Collection (Pools of Radiance).
Rarely did I touch on Sci-Fi, but still enjoyed a shooter here and there.
But, recently I have seen in my MMO's and RPG's what things I enjoy the most.
Norse Gods, Egyptian themes, the Undead.
I think the Elves and Orcs though have become a thing from my past.
I also am open to more settings. Space, weird worlds..
What do you think gets you involved? What catches you about a theme or setting?
