I doubt it's their biggest flop, but I fully expect this to be shut down by the end of the year. These Overwatch clones just can't capture the same lightning in a bottle. I don't know why Sony needs this. They have Helldivers 2 which is doing gangbusters. The game looks totally phoned by a bunch of people who were forced to make this. No love, no personality, just literally made to make money.
Why do you doubt this being their biggest flop?
Sony as a whole also has movie flops that cost way more. Destiny has also been a huge loss for them so buying Bungie was not the long term money making machine they thought they would have. Sony has been around for a long time. They have had bigger losses, this isn't the worst of them. They have had multiple online multiplayer games like MAG that flopped hard. They shuttered Zipper Interactive after poor sales of the last SOCOM game and Unit 13 for Vita. The Vita itself was a huge flop despite it's great reception and sales shortly after launch. Concord is a blip in their history of flops.
Well, it's about being PlayStation's biggest flop but yes they have many movies that fail. Destiny isn't a flop but it's not covering the costs of their acquisition. MAG and Unit 13 combined didn't cost nearly as much as Concord. Not sure if the Vita turned a profit or not but I feel like they probably still lost more with Concord.
Don't forget that Sony also acquired Firewalk Studios, the team behind Concord last year. between how bad the game did, it's budget (which I've seen numbers between $100,000,000 and $250,000,000) and the Studio Acquisition (can't fine a number). Considering what the Break-Even point can possibly be I'm thinking it might be one of the biggest AAA flops
