No one made an arrow in the knee joke yet? This forum is getting less meme-y.
If it died on this forum, it died for a reason.
Also, why shouldn't smashed constructs grant XP? I'd imagine you'd learn far more destroying a mech than crushing a dimmy. I don't know if you mean it just to discourage adventurers from being over glorified destruction teams, but in traditional RPGs, you gain Exp. for everything from slaying dragons to emptying the garbage. I think it would be interesting to introduce quests of various levels, to gain XP quicker. Something like
level 1 quest- break a wndow, kill any figure, ETC.
level 2 quest- Kill a specefic figure, crash a car, defeat any couple minifigs, ETC.
level 3 quest- kill specialist, save a princess, ETC.
And so on, and the higher a difficulty a quest you complete, you gain that much XP.
Just my overlong musing.
