Overwatch 2 is literally the exact same game. I don't mean that in a cheeky way like people used to say about call of duty or mobas, it is literally the same game as Overwatch. Overwatch 2 and Overwatch 1 players get put into the same lobbies, same maps, playing the same characters in the same engine with the same look. All they're adding is a late-2000s style campaign that reuses the PvP maps, except even that's not new because they've already had that in Overwatch for like a week before they took it back out.

And no you cannot say they deserve to get paid for the work they're putting into the new content because they (the shareholders, not the workers) have already been paid a thousand times over by the recurrent user spending in the form of slot machine lootboxes that are so egregiously manipulative and sinister that they're getting banned in several countries.
