Bring back: GNG (which includes Maximo!)
Kill: erm... tempted to say something like Assassin's Creed or CoD, but those must exist for companies to draw in shareholder money and keep existing. Witcher would kill the GDP of Poland... hm
Lemme get back to killing something. I'll try not to make it huge and annoying.
Kill: ... I thought this would be so easy but I don't want to be rude, even for the exploitative lootbox phone games. I guess Marvel Heroes would stay dead, they messed up and replaced David Brevik with that horrible CEO.
