i mean, games launched on epic arent perfect either… and devs get much more of a cut, and a bonus if its unreal engine.
FF7R for example ran poorly, stutters in directx modes due to a poor implementation of shader compilation and these bugs STILL exist in the game today last ive seen.
the developer didnt take a 30% cut for the game, being epic exclusive and being unreal means the oppisite, they got PAID and still released a buggy POS.
its a fallacy to assume if a dev had 30% more budget that a game would be bug free.
