Why? I've completed this game several times already. I'll FFFUUU- if I get TPKd, but it won't actually waste my time. I know most of the content this game has to offer, so my playthrough isn't oriented towards experiencing new stuff that would require playing through already seen content repeatedly on failure.God, playing Ironman with a completely experimental party. That takes some ballballs.
Any new stuff I'll see or not in Wizardry 8 will be restricted to gameplay and gameplay alone, and thus it will be unique and won't repeat, as gameplay is different with different parties and RNG rolls anyway.
OTOH playing ironman provides thrill that would be hard to replicate otherwise and it actually enriches the gameplay, by allowing situations I wouldn't experience normally due to feeling screwed beyond all hope and reloading.
Surviving such situations is extremely memorable and satisfactory.
I'm not a fan of ironman in general, because I consider the price of failure too hefty, but pressing player into undesirable situations without giving them feasible easy way out by reloading (ironman, delayed consequences, etc.) almost inevitably results in much richer and better gameplay than just providing them with unbroken string of boring 'awesome' successes.
It works quite a bit differently in ironman. Normally you won't really see the game over screen because you will reload much earlier (unless you really own in this game). On ironman small failures tend to accumulate and there is no "I'll try to battle this monster" - do or do not, there is no try.Hmm.... Well, even then, the likelihood of your whole party dying in combat is extremely low, especially if you powergame. It has literally never happened to me except during my first playthrough - with Nessie (I was unprepared & underleveled, but even then if I wasn't such an idiot I could have simply ran), and that weird suprise buttsex unique creature by late-late game (one that ignores all resistances to insane/turncoat etc. everyone in 1 turn).
Oh, and I savescum and keep backups exclusively in case of game/system fucking up.
