Dear @loro68, i am not envy of anybody, just i am wrting about facts and i warn this game is drive by a single person!
Thanks to @reinaldoverdu i checked this game was already existing in steemit with name steemcity and it was not so popular, after move to hive, some old steemit whales pump it just to show off that after move to hive the game become popular, but i think it is a pumping over the real support of this project.
Anyway all are free to loose all their saving as they wish, if i invest in this game i use the coins i bought with yours just to see it, so if i will loose it, no problem, it means i will win the challange...;)
