Concord is very polished. But it still seems fairly contained, a bunch of heroes, a handful of maps. Where did the 8 years go?
Firewalk studios has 169 employees as far as i can tell.
They use unreal engine, no single player campaign

Game development isn’t linear, projects get discarded in early development all the time. The development team starts small and balloons as the game gets closer to release; diablo 4 for example spent 10 years in development, 8 years is nothing special.
