In the part of my heart that hurts very much. T_T
Nah, seriously though, I don’t play GW2:
But I will answer, because it is still valid, and I think GW2 is an exception to MMOs as time sinks: I didn’t have to invest anything in GW2 (or GW) to have fun. I could play as much or as little as I wanted, and I got what I needed. I didn’t grind in GW.
LOTRO: grindy as fuck! Hence I don’t play it. When I do, I just want to run around the virtual Middle-Earth, not really interact with the game, per se. So I can appreciate it for the graphics, and some of the story is interesting, though not as much as GW2 is to me.
First person shooters: I don’t like unlocks and loadouts, though they are silly in TF2, for instance. I prefer Counter-Strike money-per-round or per-match style loadouts. Why? Because I shouldn’t have to grind to play an FPS.
So there are a lot of different criteria. Dwarf Fortress is text mode. It is deep. It gets better the more you put in. Those attributes don’t fit my life style.
