Q: What about groups of players (clans / guilds / corps)?
A: In X2OL.net players can cooperate in many ways. They can form groups, label them, and coordinate their joint work. However, being in a group is not required for any important part of the game. Players can even leave a group without losing all their property. If you join a group, you are not giving up all your wealth.
Q: Will it be possible for players or corps to buy very large (M1,M2 class) ships which players were previously not able to buy.
A: Players as well as guilds can own and fly almost every ship, including very large ships which require more than one pilot!
Q: Can players or guilds own a sector?
A: Players or groups of players can take the role of a government and even own whole sectors.
