It’s not an opinion. If you ignore straight procedural generation with no human input like no man’s sky, Starfield is very probably the biggest 3D game ever made. The fact that it’s an absolutely massive game isn’t debatable in any way.
Nobody who’s played it is making the ridiculous claim that they ran out of content. It’s fundamentally not possible for “relying on mods for content” to be in good faith.
I’m glad you enjoy the game but compared to the level of detail and polish Read Dead 2 had five years ago Starfield feels straight up antiquated imo
Red dead 2 is obscenely tiny by comparison.
Literally everything about game development is a trade off. It’s not possible to make a game at 5% of Starfield’s scale as polished as a rockstar game. The difference in scale is too massive.
The scope of Bethesda games is a huge part of the point. Nobody else makes anything similar to what they offer.
BG3 is a top down CRPG. Having 3D assets and being a 3D game with full 3D movement aren’t the same thing.
And whether it’s more content is debatable. There’s more pure story and production, with a lot of branching, but the overall amount of space (not counting Starfield’s use of negative space because of the setting) is significantly smaller. And even in terms of total number of quest lines, Starfield has a lot. Which you can get more time out of is all about personal preference. There will be people with 1000 hours in both, easy.
You can literally play BG3 as a third person turn based action game, with an over the shoulder camera. It’s entirely 3D.
