Ok so back in the day I tried out second life and now there is another one called entropia. I think from a business stand point Entropia has a lot HIGHER $$ return as the cash converts $1 - 10 versus linden. Entropia also has official banking behind it with a larger security feature so no guy is going to come along and destroy what youve done. There is a lot more capabilities i think and the sales are larger then Second LIfe. Any others input would be great!
