AAA games can cost around $100 mil or more, altogether. Here's a list: https://en.wikipedia.org/wiki/List_of_most_expensive_video_g...
We're just used to the few huge companies crowding the AAA market and turning out rather shitty games hitting you up for MTX every few seconds. BG3 is a good example of what AAA gaming should be.
Most AAA games these days are regurgitated sequels with a ton of micro transactions, etc (see any shooter), very limited choices (Diablo 4), season passes, etc. Many of them get poor reviews from gamers and they would often embargo reviews before release too just to drive up pre-order sales.
All this is to say... if you like BG3, you'll usually find that kind of love in indie games these days and not AAAs. What the AAAs give you is typically good graphics and UI polish (but not always), usually at the expense of gameplay, player choice, and writing quality. Starfield, for example, came out the same time as BG3 and was a terrible, soulless game.
That depends. If your search engine is Google, you'd get things like "The best 17 AAA games by budget to buy in 2024" or "22 triple A games for a tight budget in 2024."
