Where to download this game

Researching this website informed me that 2k20 is the version of this game for me. However, their is no safe place to download this game. No longer available on steam. Not interested in any other version other than 20. Willing to pay for this game. Any feedback is appreciated.

You can try on keyshops (grey market)
