"What do you think would be a good idea for a SINS community to get members and activity?"
Helpful, inciteful, active, fun clans.
This idea will = EPIC fail!
Honestly, that's what I see happening at this point.
Hazords attempts are valiant imo. Anyone willing to devote time and prizes to improve a community deserves better replies. However I cant help but think that the regular online community in sins nowadays have the feeling of despair that sins online isnt very strong and its becoming "sad" to be a regular sins players . I sometimes contemplate why bother with clan activity and improving my skills to win tournys and such in sins , when I can be doing it in a much more competitive game such as Starcraft where the rewards for being a regular who partakes in tournaments are better.
With this tournament which in all honesty has very little chance of fruition , its just rubbing salt in the wounds. Yes , we have the type of people willing to go that extra mile , such as hazord for this community but Sadly with all the minidumps , hosting problems and actual design of the game (not anyones fault) , this game was never going to be the online staple diet that regulars hoped it would be.
Still , treat sins as a fun pug game. No reputations , just startup a game once inawhile , join a bunch of strangers and hope nobody quits.
