Hiya!
AAA means "The very tippy-top of quality and fun", although, yeah, 'big budget' is usually associated with it. But if there is one thing that creating vid games has drilled into my head...repeatedly and without mercy...is that More Money != Mo'Bettah. I mean, look at a few games released 'recently'. None of them were "big budget"...typically a dude or three making a game for funzies that they ended up putting out there and charging $10 to $20 for. Do the same with some of the recent "big budget" games and they are overpriced AND flop/buggy.
..
"Indie" games that are AAA but made by a guy or two:
...Valheim (two guys, expanded to a few more after initial release; $22 Canadian x 4 million copies sold...do the math)
...7 Days to Die (three guys taking an idea one had over Thanksgiving; $28 Canadian x 14 million copies sold...)
...The Forest ('a small team'...I'd guess...3 to 5?, figured 'Lets do a game!', so they did; $125k initial budget, kickstarted; $23 Canadian x at least 6 million...up to 10 million copies sold)
...Stardew Valley (ONE guy!; $17 Canadian x 10+ million copies sold)
..
Then go look at the numbers for oh, Cyberpunk 2077, Warcraft III: Reforged, Fallout 76, etc, etc, etc. Compare the amount of money spent to develop and market them, versus how much money they made.
..
Anyway, long story short'ish... AAA is a signal to "be very, VERY wary!...and immediately check to see if it has and "surprise mechanics" incorporated. (...go search for "EA Surprise Mechanics" for a good, but sad, laugh!).
..
All that said...I'm "reservedly optomistic"...mostly because the company made Racoon Lagoon. A nice, quaint, fun and interesting little VR game that both me and my daughter play on Oculus. If they can keep as "focused and consistent" a game as RL, that will be very good!
