And for the second part for the people chilling in limsa what game would that be, elder scrolls, wow, guild wars 2 really dont think any would be able to grab them for anything extended. They might get some influx but not retain them.

Maybe none of those? Let me spell it out again, THESE PEOPLE ARE NOT MMO PLAYERS. They are here for a pretty dress-up game with chat functions. They are here to play Second Life with graphics that aren't from 2003.
