The Yakuza franchise is know for its beat em up combat, and Like a Dragon totally changes that to Turn Based RPG style. Usually this kind of change in a franchise is not really well seen and not always end up being good but Ryu Ga Gotoku have nailed it, there is even a reason for why all the enemies changes appearance and the changes of professions is... actually a change of profession. The story still have the qualities of the previous games, very funny in the side missions/stories and serious in the main missions. Kazuga Ichiban is a very funny protagonist and a welcome change. All about this game makes this a new start for the Yakuza series while maintaining most of the good qualities of the old ones.
Yes it is currently free but there are lots of DLCs, there are just a few which I'd consider essentials and these are the ones included in the Dinasty Starter Pack plus The Conclave DLC. In my honest opinion at this point, it is more worth to buy Crusader Kings 3 than the DLCs for this game since the base game have most of the content from the DLCs I mentioned, just play this one in vanilla to see if you like the base game mechanics since they are very simillar.
This is an artistical game, it is as beautifull as the screenshots shows. The gameplay is basic but it makes a good use of it, also the game is very short, arround 4 hours gameplay. The story is interpretative in many aspects and very emotinal. If you like this kind of game, GRIS is a worth buy.
