You’re ignoring that Capcom rebundles all of the DLC every year as sells that as the new version.
SF5 Arcade Edition was $50 retail. SF5 Champion Edition is $30 retail and that includes $1300 worth of the DLC you claim.
No one individually base the base game and every DLC individually after for a fighting game. That’s a hyperbolic situation.
You could simply buy the newest bundle every year like you suggest. And still have the existing player base. And you could opt to not buy it and play with all the new players. Every copy of SF4 and MvC3 is useless because they’re not the Ultimate versions. But every copy of SF5 and SF6 can still play the latest version of the game.
NO ONE is missing out on any content from not buying a TNMT skin. It has no impact on the gameplay or even cosmetically in the actual game. This was a fun collab for fans that you got spun up about doomsday for the gaming industry. And no one would insanely buy all 4. Every SF player knows this is a fun cosmetic to help fund the $2mil investment into the competitive scene that’s keeping this game thriving.
Just curious on your Steam Link issue, have you checked the “Change desktop resolution to match streaming client” checkbox on Steam? One of my computers is using a 2560×1080 monitor and we have it going to the Steam Link, it adjusts the resolution to 1080p to match the TV.
I’ve never tried with the 4k ranges I honestly cannot imagine the 100 mbs ethernet and cheap CPU could provide enough bandwidth without significant input delay. You might be alright with the SFF that can output your resolution and then using the Steam Link app for a beefier Steam Link.
