Honestly I wouldn't say the numbers represent a "successful launch". It got 64K concurrent players the first week, which probably going to be the best week. Assassin's Creed Odessey had a very similar number more than 6 years ago. Dragon Age Veilguard had more concurrent players (~89K), and was not seen by EA as a success. I mean, even Dragon's Dogma 2, which again was not seen as a very successful launch by Capcom, had more than 228K concurrent players on Steam. KCD 2 had more than 256K. Maybe they really have a lot of U-play subscribers playing, but I think with all these it probably can only be qualified as an "OK launch".
