I know that game is dead but my ideas on how to keep it alive are not.
Meteor is cool but it happens so rarely and is directed at top players and fractions.
Imo there should be some smaller events also, in multiple places, some of them offering rewards that top players wouldnt bother to waste time for, idk, offering boosts on low q items ? Axe q70 ?
That would give people something else to do besides talking to your favorite tree and bringing it few rocks. Also encourage exploring, made spots on map where you might meet someone in a dead world.
Few small events, few medium events, and a meteor every week or two.
