I agree with
@Christian Lowe on all fronts. I get what you're saying because getting paid $600 to be in a video game doesn't seem like a lot of money, but all these players are doing is clicking "yes" in an app and having EA Sports do the rest of the work. They aren't providing face scans (yet, we'll see what 2028 brings) or voice/motion capture, EA is just taking a .csv with name/hometown/height/weight/stats and some headshots provided by a school SID and churning through the rosters with a few tweaks here and there.
Each $600 represents one singular character out of 11,000. It'd be a terrible offer to play Lucia in GTA VI and it's low for Shedeur Sanders, but the third string nose guard at UMass and all but around 100 of those players are realistically worth a lot less than $600. I want Tennessee to win and accordingly look forward to having Nico as the gunslinger the next few seasons, but you could replace him with any other top QB and I'll be equally excited because I am a fan of the Vols and not a guy who will be out of the sport in three seasons or less. That mentality separates collegiate fandom from professional fandom, and is part of the reason why UNC Charlotte could have a team full of unidentifiable players and it wouldn't decrease interest one iota.
$3k per player would be $35MM for EA Sports to flesh out rosters in a game that isn't nearly as popular as EA FC or Madden (fewer sales = fewer microtransactions = lower revenue) yet demands significantly more initial development dollars than Madden (134 teams vs. 32). The profit margin just isn't there to go much higher en masse, which is precisely the reason we'll never see College Basketball 2026 or College Baseball 2027 since the development spend/time to do a respectable job with 362 schools greatly outweighs sales potential. Some misguided idiots will ruin all of this in a few years via collective bargaining efforts and force EA to either make future installments with random rosters (which is fine, almost everyone buying the game is doing so for the programs) or scrap it entirely.
