it's close between those two, but honestly both are such catastrophic failures we can't use the word 'flop', flop just isn't enough. Both games are criminal pieces of trash that actively seek to rip-off and con gamers.
Rotten pieces of junk the two, but TLOU2 takes it--absolutely no redeeming qualities in that title, and the honest truth is that the dishonest gaming media chose to prop it up even after it flopped, due to political bias. They kept that game afloat when it deserved to be panned, was a colossal bomb and completely flopped in gamers reception.
CyberJunk tho
