What other games are you playing?

Yes, Titan Quest was made like Diablo 2 and for the fans. And it should be said that Diablo has always been characterized by its monotony... -Arcade is arcade.

As a fan of Diablo, which is characterized by a large VARIETY of gameplay, I can say that TQ disappointed me in many ways, mainly because it didn't take the most important thing – procedurally generated locations. As a result, running past the same bush gets boring already with the third character... and you have to run through three difficulties for each... and compared to the previous one, there are many minor things, the absolute uselessness of unique blue/purple items, as well as set items, any green item with a rune will be many times better (except for Thorny Maul, it's out of competition)... the ability to reset skills for money, which eliminates the difficulty in leveling up... there is simply nowhere to spend money...
P.S. Diablo has never been an arcade game... its genre is Rogue/Action, in common parlance, a roguelike, which originated in the mid-80s and is associated with text-based games like Mud.
