Skyrim was released in 2011, which makes it the same decade as DOS2 (2017). Any definition of cRPG that doesn't include Skyrim is just cherry picking to make a point.
Note that I am not claiming anything about the relative merits of Skyrim vs DOS2, just arguing that you cannot call DOS2 the only mainstream CRPG of its decade when Skryim exists.
Fine, what about the pedantic definition of : RPG with top down perspective that you usually play with a mouse? Actually that would contains Diablo 3 (a hack&slash) and Lost Ark (a MMO) whose are probably more popular and have real time combat, but I am not here to fight a linguistic battle.
