I think we’ve all played with LEGOs at one point in our lives and while they’re fun to build, there’s not much you can really do with them afterwards other than display them, or tear it all apart again and build something else. That might change with LEGO Super Mario as it looks like this is an actual LEGO set you can play with.
You do so by constructing levels and having Mario run through them as you would in a Super Mario video game. The LEGO version just translates that into real life. This seems like a pretty neat idea and one I’d like to see LEGO expand upon with their other sets.
Aside from the trailer, there isn’t much more information to go on so hopefully there will be more information soon.
