Market Contents for open world games

Hi everyone,

I would like to know any tips & tricks for open world game and also are there any market assets available for easing the development of an open world game?
Hoping for suggestions :slight_smile:

Tip: be a company.
Trick: have millions of dollars to expend.

I just find funny how “open world” is becoming the new “how me makex mmo” thread :stuck_out_tongue:
