This first video is of one blokes complete PAL collection. That's every single game released in Europe.
But this guy's collection not only takes the cake, but the whole bloody picnic. Just about anything and everything worth owning is here: including a Jet Set Radio box art I've never even heard of let along seen before and loads of the many different special edition consoles. If you check out his account on youtube he also has equally gigantic Saturn, SNES, Neo Geo, Mega Drive and master System collections, all displayed wonderfully in a bizarre room that looks like one of those crazy Akihabara shops.
