Guild Wars 2

If you complete the dungeon run with less than a certain number of repairs, your money is refunded in addition to your dungeon reward.

Incentive to stay alive? Check.

Doesn’t apply to the “die and zerg” strategy? Check.

What that number is might depend on dungeon, and I wouldn’t presume to know what that number would be. But, I do think that having a little cushion for messing up is a good thing. Being forced to cough up repair costs because you borked a dodge isn’t good game design. Give players a little bit of a net and it’ll help with the overall dungeon experience, and maybe get rid of the “Oh Dungeons are just a big money sink” notion.

I’ve been wanting this for a while now. A full repair at the end. As for stopping death zerg, respawn timer, another simple solution. Maybe even kick people from the dungeon if they die whilst naked?
