Lol younger one, you forget one generation of RPGs.

I agree that in most hack'n slash games (or kill+loot games), inventory is an issue to manage for item collectors like me, but is mostly the fault of game content and economy designers. When loot is scarce, you have much less issues with the inventory.
Inventory management (and muling) is precisely why I stopped playing at Titan Quest, Sacred, Guild Wars 2...
