a lot of reasons. i've been here for about eight years for now so i should have a lot of
*Great community. This is the most unique community ever, for me. And i enjoy being a part of it.
*Roleplaying - for the most part i am in the roleplaying community, be it the ladder, hadrian's projects or the SE:L. Thats actually why i came here.
*As you all said, no uber-strategy. A good example is AoE - build like 30 catapults or balistas and go, kill them. no fun.
*Each time something new: AI or human players each time i face new challenged, never repeated.
*Friends! I have a lot of friends from this community
*Strategic challenge - it it just fun to invent the way to crush that planet, kill that ship or best that fleet. Its different each time and one has to ponder to great lengths what he's doing, what he will do and what others are doing
the list could go on but those are the main parts of it.
