Entire Yakuza series is like one of those slightly underrated/hidden gems, most people just dont play because they assume its some weebo japanese crap. Until they do (play it), then they realise they enjoy the game :)
About the map/world:
I actually prefer smaller maps, if they are well used, and crammed full of stuff.
Rather that than a gigantic baren and empty world.
"Well, there you have it. The Yakuza series has a new fan,...."
hell yeah :)
