just 2 of this games? well the mass messaging is very important for a guild, i played IO(in Hungarian world my alliance were the 16, until i quit and the alliance have stopped existing), i played the galactic imperia, hodito(conqueror), tribalwars(for more than 3 years),WOW, Linage 2, metin2(i quit because of this game i forget my meal on the gas and we have to paint the walls) 9 dragons, and this are what i can remember for now. and all this games were nice because we made a very friendly tribe, guild, alliance, clan... and there you need to mass message, this game is very nice for now, but its lack the comunity feeling, i hope only for now
