Warhammer 40,000: Space Marine 2 has been delayed until the second half of 2024, but we'll find out an exact release da…
A delayed game is eventually good, but a bad game is bad forever. (Very rare exceptions apply).
Duke Nukem Forever is the exception, and to be honest I'm not even sure if it counts as a 'delay' when they started over with new game engines multiple times...
Yeah development hell is a rough spot. Sometimes it can turn out great projects (Doom 2016 is a decent example, when it was originally meant to be Doom 4 it was closer to a call of duty style game) but alot of the time it turns into a mess. You already mentioned Duke Nukem forever, you also have Spore, Too human, Final Fantasy 15, Dead island 2, etc.
Depends on the proximity of the release date and the amount of delay honestly. A delay of only a few weeks very close to release tends to indicate that the release is going to be a mess, fortunately it is not the case here and the delay is significant.
I can think of only one time a two week delay didn't result in a broken game anyway, but how much of that was because of the delay is impossible to know.
