I would argue that is not true. I don’t see many Indie games that match AAA games from 2010 in polish or content, honestly. Maybe there are a few, but I cannot think of any off the too of my head. Most are like AAA of 25+ years ago.
On a technical level it may be achievable that an Indie game matches a 2010 AAA game, but I think mechanically speaking that has not happened yet. Indie games have a hard time even matching the content and polish of 20 year old games from 2005. Where is the Indie Resident Evil 4, or Elder Scrolls III Morrowind? Some Indie games try to compete, but they either aren’t polished enough, look like they released in 1999, or are too short in content to compare to those games.
I only bring up RE4 since it released in 2005. Morrowind is even older at 2002. My point was more that there aren’t any indie games that match the content or polish of those games, as old as they are.
Its mostly a limit of indie in general. Not enough money or time to match AAA games of even 20 years ago. AA absolutely should be at minimum matching 20 year old games, but even the funding AA gets should be enough for AAA games from 2010.
