Lego never dies. The imagination is limitless, within the lines of the software or real life Lego blocks. At some point I think they should have, "riftable bases". Something a bit like Dr.Who's TARDIS. Only we wouldn't call it that for legal reasons, at least not without forking out royalty money. It would basically be like your own "cave", that could be landed anywhere on the map. Bigger on the inside than the outside. I think this move would bring back more Lego traffic, everyone would now have the task of developing their, "inner world". It would stray from the formula of, have a newer more powerful boss that you need newer loot to defeat. Would appeal to the builders perhaps more so than the brawlers. I think the spirit of Lego is more about building, since we can have both we have both.
