good idea , is has been asked before for surveys on login , or after finishing the MSQ , a dungeon (was the dungeon well populated? too much trash ? bosses were fun? your job was usefull ? ) , crafting , and of course events (lords of vermilion , chocobo racing)...

as reward for the surveys , give some gil? materias? a pet after helping with multiple surveys.

(B&S has surveys too and is awesome, u feel important!)
