Allods Online cash shop at launch (aside from the huge debuff only removable via cash shop items) was how much it used to cost just to make a minor upgrade to your inventory storage. The prices have since changed, of course, but the irritation at inventory management was obvious.
Nearly every game has to decide how much of a management aspect should be involved and the right amount of space for a given character in any stage of their career. Moreover, these aspects usually change with time, as stack sizes increase and decrease with patches. Some players see space management as a relic of games like Dungeons and Dragons, which used it to try and maintain realism in broad strokes. Others see it as an obnoxious limitation on gameplay that's long ceased to have any connection with its original purpose.
So what do you think? Is inventory management a good thing, or is it one of those gameplay elements you'd like to see go the way of the dodo?
