Two things seem to be considered parts of the game: Hero Saves and trading. The last due to ridiculous loot and inability to have more than one piece of each kind of armor or weapon (so no loot trade at all).
The Hero Save seems to me meant to be exploited as well - what if you fail on a mission? The fact that you keep what you've got until the save seems confirming that there was an intention, even encouragement to use that feature (because in light of reasons i mentioned it's actually even not an exploit).
The fact that using that feature too much may ruin your game (not because it becomes too easy but because it starts to crash) seems to be rather a bug than deliberate intention. That course wouldn't be considered a right way of action in particular societies (neither in general programing nor on game makers' communities).
