It's very interesting. I played that new-ish Marvel: Cosmic Invasion game and recently played Fight 'N Rage. I believe both are built in the exact same game engine. Fight 'N Rage, which is undoubtedly the better of the two games (although both are quite fun) had a tiny roster. I think there was a single primary developer, and then one guy did the music and maybe 1-2 other people helped with things. The Marvel game was made by a "real" studio and had tens (hundreds?) of staff to build what was effectively a slightly lower quality game. (although the Marvel game had a much smaller staff than anything like a modern AAA release.) Famously, Doom and Quake were made by quite small teams.

I don't know what the answer is, but there just seems to be unavoidable bloat all around. Staff, cost, complexity, system requirements, etc.

Doom came out in 1993, all teams were "small" by 2026 standards.
