Few weeks ago I saw ECO.
ECO is a MMORPG game where you prevent a meteor that moving towards earth from an intersection.
Sound weird, but here's the catch; you have to advance quickly by developing new technologies when everything you do is influencing the environment, so you have to be careful to maintain balance and not destroying the earth itself.
I'm looking for partners for this game, and if anyone heard/played it before I want to hear about your methods/tricks/strategies you've found out.
If it is the first time you are hearing about this game, I want to hear from you too.
